Bderick67;1457172; said:IMO you will be lacking in bio filtration. Magnum are not very good biofilters, but you can fill the media container of the magnum with bio max, this will help. Your fluval 205 is only rated for a 40 gallon tank. I would look into upgrading one of the two filters you have now.
The water would be top notch with an XP3 or a Whisper 10. The bacteria colony, given enough space, will grow only to the size at which the ammonia produced in the tank can maintain. Beyond that, you will have bio-media that is empty, and just taking up space. Which way did you waste more money?ccdoido38;1457595;1457595 said:oh; but not cleanliness wise right?
i can see that it would blow the fish away if you were to get a XP3 on a half gallon tank. but the water qualoty would be top notch wouldn't it?

Bderick67;1458094; said:I misread your OP you have a Penguin 350 biowheel, right? This puts you in a little better sitsuation for now but once you cichlids are full grown they will produce alot of waste. There will also be alot of small uneaten food particles that will also contribute to the levels of waste. I would look into upgrading your canister filter. When you do this you will be able to move the media from the 205 into the new canister and add much more biomedia along with it.
He is not asking about filtration for "five tiny fish" as you put it. He is asking for when they are full grown.

Scorponok;1458690; said:Right now your turnover rate is actually 5. (350+110)/90, which is good enough in the range for freshwater. If you want to upgrade filteration you should upgrade you tank as well. But even with a bigger tank with 5 turnover rate is good enough.
I personally think those five fish can live in your 90g for life. Three of them max at 12" and two of them at 6", while the current tank has enough width for them.
