snakebite Took the valve assembly off and found this...



Called the lfs to get another one. I put the new one on but the results are the same. I'm pretty disappointed with the output from Rena/filstar and their XP3. It looks like I have to put an ugly powerhead in the tank just so the water circulates. I might just get another canister filter. If I use a cerge Co2 reactor, I'm sure the flow will decrease even more.

Thanks to everyone who try to assist and the members who PMed me regarding this issue.

I can't compare this filter because I never had one before but if people are using it on 75g + I'm sure there should be plenty of flow for a 40g. The spraybar is useless, and even though I put it about 4" below the water surface the flow barely trickles the top.
Seeing how much 'built up junk' is in there, I'd say you might be getting close to replacing a impeller... or a clean up.

dmagerl Mine is on a 55g and I get plenty of flow. But I should say that its an old model XP3, bought before the company was sold.

I use the spray bar about 4 inches below the surface, pointed upward and get plenty of surface agitation.

Common sense, right? Well, once the plug is removed there is no water circulation coming in or out of the canister.

Thanks for chiming in mott. Can anyone with an xp verify regarding this plug?

Impeller has no visual crack.



There's another problem...

Took a basket and a half full of rocks out and still the same flow.

When I get home, I'm going to check the valve assembly(?). A member suggested to check that out. Sheesh, what could it be or is this all the power this xp3 has?

cturner Honestly I think you have things packed too tight. You need water movement through the filter baskets. It's like trying to push water through a plastic bag with pin sized holes. It isn't going to work well. You need to allow some space in between the media and the baskets. If that doesn't work I would call Rena. I've never had a problem with my XP3 and like Rob in I have to clean mine every 3 weeks and the water I dump out is brown as dirt!

wendyjo Next time I do maintenance I'm gonna have to look for that plug as I never noticed it before.

What plug are you talking about? I swear I've had my xp3 for 5 years now and never noticed a plug.
After rearranging media trays, I got better flow but didn't do well with the spraybar either.

If you take a look at the picture below you can see the intake hole on the left then the output hole on the right. I was referring to the black plug on the output.

like the other poster stated you must have The Rens's course filters on the very bottom tray & not the top tray....

on my Xp 2 I have the 2 course Rena filters on the bottom tray with 12 Rena Bio stars on top of the course filters, then on my top tray I have a small bag of JBL ceramic rings and then the Polishing filter on top.

I get great flow. I also clean the Rena about every 3 weeks as I can not go any longer than that.....it gets pretty dirty.

Good luck
Moved the sponge tray to the bottom, the result is better flow but still not to its potential. I'll try removing a basket of rocks and use ceramic rings in one tray.

Maybe I'm just expecting too much from this xp3. I still don't see how this could filter larger tanks when there's barely any circulation/filteration in my 40g.

jnunn I had the same problem with one of my XP3s a couple of weeks ago. The flow could be low or high or none at all. I found that one of the nylon balls in the shut off valve was not rotating with the leaver. Ended up purchasing a new valve assembly which I did not use. If you need one contact me by PM.
