Best Biological Filter Media?

[JoeyGeeze]

Hey all.... I have a fluval 306 running on my tank and I'm thinking about removing the carbon section. The filter has been running for about 6 to 7 months, so I'm sure, from what I have read, it's run it's course. Is there a good filter media I can replace it with? I see theres rings and balls and other types... Will I see any added benefit by adding more bio filter media? Thanks in advance!

In my fluval, I only run biomax, except in the very first chamber I filled a media bag with some plain old pillow batting.

In my 206 I have as follows.

Bottom cartridge - sponge and biomax
Middle cartridge - biomax and polishing pad
Top cartridge - biomax and Phosphate remover

No need for carbon unless you suffer bad smells or medicate your tank.

Phosphate remover I only use due to high levels of phosphates in my tap water.

Ok awesome, thanks for the replies! I may pick up some Biomax from petsmart today. Is there any added benefit to doing so? Or is it just another spot for bacteria to colonize on?

 

[paytertot]

It's specifically for BB to colonize on.

The store was sold out of biomax so I just purchased it online. I'm going to replace the carbon in the first cartridge with the added biomax... Sound about right?

I've heard good things about Purigen, I may look into that!

Nothing but blue sponge material after the prefilter. Works great, almost never wears out.
