Rena XP2 is making a high-pitched squealing noise

by Morgan
(Seattle)

A few days ago my Rena XP2 filter starting making a high pitched squealing noise intermittently. This wouldn't be much of a problem except that my aquarium is in my bedroom and is making it hard to sleep. I've taken the filter apart and cleaned it several times, but the noise won't go away. My filter is about five years old, I thought that some part might just be getting worn. I was wondering if you guys have had or heard of issues like this before, and if you did, could you tell me how to fix it?

Thanks!

A: It sounds like the Rotor/Impeller needs replacing. A five year old filter could probably use some very careful inspection for cracks in the inlet/outlet accessories, orings should also be inspected and replaced if needed. If you don't get a good siphoning action going from the aquarium you can starve the motor for water and this makes the rotor/impeller run hot and eventually wears it out. You can find parts at the Rena Aquatics Outlet

Rena Filstar is not sucking water

by rick
(so cal)

the water suction is not very powerful it works but not to full potential does anyone have advice

A: This symptom has to do with priming and has been discussed already. Please review previous posts at the bottom of the Filstar FAQ page for suggestions. I also advise viewing the video on startup at http://www.MarsFishcare.com

My filter won't prime and start running

by Barbara
(Rochester,NY)

Ever since I bought this filter I have had a problem with starting it back up again after cleaning it. Normally it requires being taken apart and resetting the gasket 3-4 times before it will work. Today I have been trying for over an hour and it won't work. My filter is 5 years old or so. I am assuming I need a new gasket any advice??
Thanks
Barbara

A: If this filter is setup properly it is one of the easiest filters to restart. It was designed from the beginning to overcome many of the problems in maintaining an external canister filter. First, please review the other FAQ's listed after the new FAQ form. There are many questions and answers about flow listed there.

Generally, this is a priming problem you describe. As the water is being pulled from the aquarium and into the filter it is not filling up the area where the rotor impeller sits. This causes the rotor impeller to spin with no water or not much water as needed. The rotor/impeller is lubricated by this water and also operates at its maximum power if the rotor/impeller chamber is full. So,until you can identify where the air is leaking into the intake side and fix it; you will have this problem. There is an excellent video which anyone having priming problems should see. You can see it at MarsFishcare.com

noise from rena xp2

my rena xp2 makes a sound like trickling water it comes from inside the filter canister it will run quite for ages and then the noise starts again, there is no spitting from the spray bar just the noise from inside the cannister.
i've tried dissconecting the pipes and filling it up again and it runs quite for a while and the noise starts again.

A: This is caused by a leak of air into the inlet. My guess is that you also have an air bubble in the top of the canister. This has been covered many times already in the FAQ section. Please read through that information and if you still have questions please contact us again. Look for questions related to priming, rotor noise and bubbles.

The filter does not pump.

by Chuck Smith
(Stanwood, WA, USA)

I have followed all the manual directions. The tank fills within a quarter inch of the top. The motor runs, but then no water is pumped.

When I fill it manually full the motor runs, but still no pumping.

A: Your problem is most likely caused by poor priming. This topic is covered extensively in the FAQ section. You can also find help for this at the manufactures web site MarsFishcare under the Rena section. They also include a nifty video that many hobbyists find useful in identifying this type problem.

Is there suposed to be air in the filter?

I have a xp3. The flow seems normal and there are no bubbles comming out of the discharge. However, looking at the filter from the side I can definately see air, about .200 below the motor housing. Is this normal or is there a problem? I installed the filter per the instructions. There's no loops in the hoses and the filter is below the tank. The filter has been running for about 3 months and it has always had some air in it. I tried shuting off the filter, like the instructions said, to purge the air, but there is still some air that stays in the can.

A: First, please read some of the other FAQ's that have been submitted and answered about air in the top of the filter. .2 is not probably going to affect anything for now but you may have a very slight leak of air from somewhere. If more air appears eventually this will cause other problems as outlined in previous FAQ's.

Do I need a new motor or impeller or both?

by Rocco
(Downers Grove, IL)

My Rena XP2 quit pumping. It's making a rattling sound. Can you tell me if I need a new motor, impeller, or both?

A: You don't need a new motor unless it was damaged by the noisy rotor. You may not need a new rotor either. First, please review the other FAQ's listed after the new FAQ form. There are many questions about flow listed there. Generally, this is a priming problem you describe. As the water is being pulled from the aquarium and into the filter it is not filling up the area where the rotor impeller sits. This causes the rotor impeller to run without as much water as needed (causing the noise you describe). The filter is lubricated by this water and also operates at its maximum power if the rotor/impeller chamber is full. So,
until you can identify where the air is leaking into the intake side and fix it; you will have this problem.

Rena Filstar XP3 barely pumping after new rotor installed

by clint lewallen
(wilmington nc)

I have a Rena XP3 Filstar. Just replaced the rotor/impeller because it was barely pumping water and making noise and its still doing the same thing with the new rotor/impeller. Should I replace the XP3 Motor? The motor has the old bearing in it.  I can't get it out to use the new bearing with the new rotor/impeller. It is over 2 years old.

So, until you can identify where the air is leaking into the intake side and fix it; you will have this problem. Getting the old bearing (BTW this is really a bushing and does not turn, just supports the rotor shaft) out is not an issue. Just keep the new bearing as a spare.

Rena Filstar XP for turtle tank not pumping

by ray
(matawan nj)

Its just not pumping good. Very slow even with no filter material inside. The filter is 1 yr old.


A: I can only guess from your info but I would bet the unit has air in the top also. This results in the pumping chamber not having enough water to pump at a good flow. It is more of a problem in amphibian applications since you have more places for air to leak into the system with the low water levels found in this type setup. Find your air leak, make sure you always restart the filter with an empty canister and this should resolve the issue.

New Filstar XP3 has Cloudy water w/ heater

by Raquel
(Angier, NC, USA)

I own a 75 gallon turtle tank. Two days ago I put fresh water in the tank and yesterday I installed a Rena Filstar XP3, attaching it to the intake line of my Rena Heater. I awoke this morning to find my tank much cloudier than it was last night. (However the temperature was a lovely 78 degrees of which I'm very pleased with. :D) I found a little bit of seaweed around the intake port and I cleaned that out but I'm not seeing any improvement in my water quality. I also exchanged about 25% of the water. The filter is running properly and now there is nothing obstructing the intake. Can you give me a clue as to why my water isn't "crystal clear"?

A: A new filter must "cycle". If you are not familiar with the term it has to do with establishing a strong and vibrant colony of good bacteria that is used to break down waste in an aquarium. Turtles are very dirty and this process takes about 4-6 weeks in a new tank. You can speed up the process by adding bacteria to the tank. We recommend the following for a turtle tank:

Intake Not Effective

by Darlene
(Waynesville, Ohio)

Hi,

I have a Filstar XP3 in a 30 gallon tank with 15 gallons of water (approx) and 2 4 inch turtles. I don't believe that my intake is working properly. I have watched even the smallest partical of food and other matters by the intake vent and they barely stir and certainly aren't being sucked in. The water pumping in seems to be fine, but probably not at the volume it should be if the intake isn't working right. I am wondering if I have TOO MUCH filtering material in the filter. In the bottom section, I have two of the coarse black sponges. The middle section I have the clay cylinders and the the medium white filtration pad. In the top section, I have the fine sponge and the fine fitration pad. Is all this filtration keeping the intake from working properly? I would appreciate your thoughts. Thank you.

Darlene Southern

A: I would advise changing the media configuration first. If you need ideas on this there are many previous FAQ's and Q&A' related to turtles. Reading through this will give you the answers but if you still have questions please contact us again.

XP2 vs XP3

by Nancy
(New Jersey)

After alot of on line research I'm convinced the RENA Filstar XP filter is the one to get! I plan on setting up a 60 gallon aquarium (48x13x24?)community/fresh water fish tank. If all goes well I would eventualy like to add a few angels also. Are there any benefits to using the XP3 on this size tank or would it just be over kill? Thank you in advance for your help.

Nancy

A: The only advantage is the extra basket and higher flow rate. If you think you will overstock the tank then these extras might be useful.

Water clarity in my aquarium

by Jim

Q: I just installed my X3 Rena last weekend and I must not have done something right. All the reviews
I read the people were amazed how clear the water was using the Rena Filter.

It also seems I am getting a film on the glass so I am thinking there could be other issues going on in the water. I had just done a water change and things were crystal clear prior to swapping out my filters. ( I had a Marineland 360C and after replacing the head 3 times because of leaking I gave up )
In the interim I am also going to deal with the Phosphate Level.

A: Hi Jim,
The best place to get answers to this type question is from the company/dealer where you purchased the item since they are more familiar with your setup. As an alternative you can contact the manufacturer. In the US that is Mars Fishcare (formerly Aquarium Pharmaceuticals, Inc.) This is the information in the product manual or literature that came with your product. If you don't have that information here it is again:

Email: docwellfish@aquariumpharm.com or Toll Free 800-847-0659

PlanetRena is an authorized distributor of Rena products and we are happy to answer questions about replacement parts or additional parts needed to complete your setup.

Is there supposed to be air in an XP Filter?

by Bill
(Charlotte, NC)

My filter blows bubbles, surges and has about 1/2 inch at the top of the canister. Is this normal?

A: Bubbles, noise from the rotor/rotor impeller area such as grinding, squealing, clattering, etc, are all caused when the pump is not receiving enough water to keep the rotor/impeller lubricated.  This problem is caused by poor siphoning and flow from the aquarium. In most cases there will be 1/2" or more of air in the top of the canister. To fix this you must find where the air is leaking into the system. The most common causes are:



  1. Improper restarting of the filter after cleaning. Always start with an empty canister

  2. The quick disconnect is not seated firmly into the top of the canister before the handle is closed

  3. Either /or both the quick-disconnect and canister orings need replaced

  4. A Lose connection on the intake side above the water line in the aquarium is letting air leak into the system

  5. An air diffuser (bubbler) is too close to the intake allowing water to be drawn into the system



The best place to get answers or ideas on how to fix these problems is by visiting the manufactuer at Mars Fishcare. They have an excellent video that covers visually the set up of a filter and some common pitfalls.

by Matthew
(Wallingford ct)

I just moved my filter from my old house to my new house. After I set up everything up I primed the filer and watched it fill up almost all the way to the top. However i can still see air in it and when i tip it a few drops of water came out from the filter. Any advice?

Rena Filstar XP filter will not run after routine change of media.

by Merrit Schwartz
(Philadelphia PA)

I cleaned the intake and output tubes, then used the funnel to fill the intake tube with water, but the canister is not filling up. I get bubbles coming from the output side but that is it.

A: From your description I think a step is missing on restarting the filter. Please visit the Mars Fishcare site and view the video on the operation of the filter. Once the intake tube is filled from the funnel, you place the Quick Disconnect into the slot, push down the handle and water will begin flowing into the *empty* canister. If your canister does not fill completely with water (no air in the top of the canister)then the unit is not priming correctly. Please contact us again or call the manufacturer's toll-free technical support line at 800-847-0659.

My Rena Filstar XP filter is not pumping at full capacity

by Stewart New

Im using an XP3 on my 55 gallon overflow tank, and I do not believe that the pump is working fully. Detritus settles on the bottom of thank, and the filter's flow is not strong enough to pull it out.
> How can I know if the filter is working fully? An XP3 is not too small a filter for a 55 gallon tank?

A: If the filter is working at full capacity you will receive a strong flow of water from the outlet (assuming the control valve is wide open). My guess is that the filter motor is being starved for water. This could be due to poor priming, or a leak of air into the intake side. If you have an air pocket at the top of the filter this is a sure sign of an air leak in the system.

Rena Filstar shuts off after running only a few minutes

by Rick

I HAVE A RENA XP-4, IT WILL RUN FOR ABOUT 2-MIN. AND STOP SO I HAVE TO UNPLUG IT WAIT 30-MIN PLUG BACK IN AND SO ON CAN YOU HELP?

A: It sounds like the motor is overheating due to lack of water. A sure sign of this is if you have an air pocket in the top of the canister. I also urge you visit the Mars Fishcare site for troubleshooting info along with the answers already in the FAQ section at Planet Rena.

Rena Filstar XP making a spitting noise with water

by Kevin
(Duckworth)

We have owned our XP1 for approx 4 years. Recently we hear a lot of spitting noise coming from the water return spray bar. Its almost as if the filter is not sucking up enough water and there are little air pockets. I checked all the seals and they are tight. Is the motor dying? We also recently have had a very difficult time priming the filter after cleaning. We woke up this morning and no water was coming out the return bar so we unplugged the unit.

A: If the filter is 3-4 years old you will probably need to replace the rotor/impeller. Copy and paste the link below to go to that item:

http://rena-aquatics-outlet.planetrena.com/Rotor-Motor%20Parts.html

You may also have a leak on the intake side of the filter which is not allowing the unit to fully prime or maintain prime. There is much information on this problem at the bottom of this page.

Does my Rena filter have a biological filter?

by josh
(tennessee)

i am switiching to a saltwater aquarium and don't know if i should add a filter with a bio wheel

A: Yes, the BioChem Stars are for biological filtration. You also get biological filtration from the foam pads as well. Whether you need additional biological filtration is more a function of the bio load on the filter.

My xp3 is not filtering well. Flow out of the canister is very slow.

by Fab Dugal
(canada)

The impeler is in fine shape. the lines are not clogged, and I don't know what else to check. Thanks.

A: There are many things that can affect flow. I would advise contacting your local aquarium dealer about the problem as they will have better knowledge of your system. If you want to check things out yourself remove all the media from the baskets, put the filter back together and restart. If you get good flow, you know the problem is in the filters. You don't say how old the filter but if it is more than three years old you may need to replace the rotor as the magnets do lose strength over time. You should also check at the bottom of the FAQ section for the most common questions and fixes for the filters.

I can't get any flow through my XP3 filter.

I took avereything apart and reassembled. There are no blockages or leaks and all line syphon freely into a bucket when I disconnect them from the motor cover inlet/outlet tubes. This unit has worked perfectly since I purchased it a little over a year ago. I primed it to make sure everything was flooded and full of water. The motor turns freely. (I have 2 filters like this one and the other one works great). I disconnected the discharge hose and held it over the top rim of the tank. When I start the pump, I get a good flow of water for a couple of seconds but it quickly reduces to a trickle. I even placed the pump section in a sink with about an inch of water and it pumps great.

Any suggestions???

A: Please read the FAQ's in this section that relate to flow. I know they aren't organized well right now but we're working on this to make this easier. 2nd, if you have other XP filters I would be swapping out components until you isolate the problem. 3rd, if you have not viewed the manufacturers video at Mars Fishcare, I urge you to do that. I can't tell you how many times people who have multiple XP filters tell us they learned something new after viewing the video. Finally, you should also contact Mars Fishcare technical support if any of your filters are still under warranty. If you don't have that number you can reach them at 800-847-0659.

I am getting micro bubbles out of my Rena xP3

by Sam Romagnano
(Elgin, Il)

I have had this filter for over a year and have never had problems until a week or two ago. It started producing thousands of Micro bubbles out of the return pipe. When I unplug itand run a small over the tank filter the bubbles go away with in a few minutes.I have cleaned all the pieces. Replaced all the tubing as well as the foams, filter pads and the Bio- chem. Still i am getting these bubbles. It clouds the entire tank. What can I do to fix this problem?

A: The answer to this question has been posted many times. You have air leaking into the system from the intake side. How to troubleshoot this problem posted at the bottom of the Fistar FAQ Page. I believe it also covered on the manufacturers web site MarsFishcare.com and at the back of the Filstar Manual.

How do you get the Rena Filstar XP filter to run quietly?

by Mike
(North Carolina)

I read some reviews on how quiet the xp2 is and others complain of noise. Unfortunately I have a noisy one. I have 3 tanks, numerous canisters and been keeping fish for 35 years. I know when a canister is noisy.

Can any part of the impeller assembly be replaces for quieter operation. The noise is definitely from the impeller, not air.
Thanks

A: Noise from the rotor/impeller area is most often caused by lack of water in the rotor/impeller well. Filters that have this situation will generate more heat and the rotor/impeller will vibrate more as is spins, transmitting this noise outside the filter. If the filter was noisy from day one you may just have a slightly mis-matched motor and rotor/impeller which generates more vibration. This problem might be fixed with a new rotor/impeller. If this doesn't fix it you can always return it (up to 30 days after purchase) for full refund.
