The vendors say to replace every three months (of course...they want to sell more product)...but I've heard some people leave it in there forever. I see no reason to really change it as long as there aren't major clogs, etc. in it....I think I've had Biomax in my Fluval for about 3 years?!?! :rolleyes: I don't think bacteria really care....

before I can answer, is bio max the ceramic rings? If so then you taught me something new and fluval is F.O.S. If one can use a sponge for over a year then ceramic should last way longer IMHO.

Right, it's the ceramic rings used to promote bacterial growth. I just don't see any reason to remove it. I guess one could say the surface properties of the rings could get smoothed over, and therefore less room for the bacteria to colonize...but that's a stretch.

considering that they use ceramic to sharpen knives, protect space shuttles, and for lifetime brake pads I'd wonder if it was more to do with them getting clogged up, though I couldn't really see that happening easily if maintained. I am thinking they will out last teh canister lol.

The ceramic isnt going to break down in water. So as long as you wash them off once in a while, there no reason to ever change them.

Exactly. I've had mine for 3 years. Added more biomax to my AquaClear filter also, so I have the stuff in both a Fluval and AC. It sure does beat forking over more dough for some resin or other media to remove nitrites or ammonia!

They should last forever. Just swish the basket out in a bucket full of tank water every now and then so no nasty crud reduces the flow of the filter.

If there is a good prefilter before the noodles they probably won't get dirty very often.
