Biological filtration questions

[[enjoyable_attempt]]

What can I do, or add to improve my biological filtration, I'm thinking of making a sump mainly for it, but if there is a easier way I would like to take that route.

Throw me some ideas, and what you think


(On a side note, I have the fluval fx5 with its basic 3 stage media on a 225 gallon tank.)




-EDIT- Just figured out I posted in the wrong area...sorry

i say emp 400's with bio rings and bio wheels should add some area

I do not see many ways around it. But some guys are experimenting with plants only tanks. Just take a look at Severum1's thread " My greenhouse for fish".

Of course it all depends on the size of the thing you want to do...

Sponge filters work if you don't mind the clutter in your tank.

My personal view is that a single FX5 provides a somewhat insufficient capacity for biological media with the tank size you describe, assuming a robust population of fish. However, to squeeze out as much biological activity as you can from that single FX5, I would eliminate all pads and chemical media from the three media baskets and fill each chamber with Ehfisubstrat Pro.

that sounds like it will turn into a nitrate pump unless cleaned constantly. which will do no good for BB. unless you run a foam prefiler on the inlet.

Bingo. Best bang for the buck when it comes to bio filtration IMO

All of my filters are nitrate pumps that are fueled by ammonia

right but what i am sayin is removing the mechanical filtration will cause the bio filtration to become poo logged.

Gotcha, I'm just being difficult I usually have to jab at the "nitrate factory" comments haha.
