I know what AC is and how it works. What exactly does it do in an
aquarium? What is it adsorbing? Not the ammonia, NH3 or NH4 is it?
So what? Color, odor?

Thanks

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

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.

Partial water changes. I gave up charcoal ages ago and don't miss it.

Nothing. With partial water changes you don't need anything else in the
filter but the sponges and stars.

Biological filtration and good husbandry.

What is "biological filtration"?

That the process where certain bacteria turn ammonia to nitrites, then
another bacteria turn the nitrites to nitrate. Both ammonia and nitrites
are toxic to fish. Nitrates are not unless excessively high.

One does not filter "in" or "out" bacteria. Nitrates are not
biological, they are just chemcals. The bacteria are the active
agents.

Every pond is full of bacteria, all doing special things.

No filter, I can imagine, would be classified as "biological
filtration." Why would one want to filter out bacteria?

Your semantics are very limited.

Biological filtration is a widely used term to describe the natural process
of the nitrogen cycle. It has nothing to do with the "filtering out of
bacteria", which doesn't even make sense. Bacteria will adhere to any
surface where it is able to obtains the means for it to survive--it exists
in every part of your filter.

Biological filtration describes the action of biological organisms
(bacteria) on organic chemicals (nitrogenous wastes) as they convert them
into various, and progressively less toxic forms.

A natural process that occurs everywhere in nature that involves the
recycling of nitrogenous byproducts into various forms. The cycle is
incomplete in aquaria and generally is limited to the conversion of ammonia
into nitrite and nitrite into nitrate.

The first two byproducts are very toxic and can kill fish in short order
when found in quantity, the last byproduct is many times less toxic than
the others and generally only increases stress levels and the chance for
shock and infection when found in very high quantities.

In nature nitrate is further converted into nitrogen.

Without biological filtration every fish in your aquarium would be dead
right now.

The subject of this thread is "activated Charcoal.

You have taken some effort to describe, what appears to be, a natural
process. Even mention of "biological filtration" would appear to be
off topic. Mechanical filtration and their relation to charcoal would
be close to the subject.

Why did you insert your "biological filtration" know how into a
discussion about "activated charcoal"?
