This is what I've been hearing about charcoal... If no charcoal then
what?

I have a clown loack tank, a ciclid/cat fish tank and a spotted green
puffer tank all with AC 500's.... What would one use along with the big
sponges and bio stars thingies? Peat for the CL's- soft water? This
non-charcoal thing is new thinking for me...

Thanks, Karl.

So what? Color, odor?

Not much and not for long. I quit using charcoal.
