Hey, what is a filter carbon

we added the white spot treatment and it told us to remove the filter carbon ? what is it and as we have already put it in should we remove it

what type of filter do you have
carbon looks like black pellets your filter might not have it init

I'm not sure but it just has a sponge at the bottom , when we looked inside it didn't have pellets

carbon filter is usually a net bag full of black carbon in your filter not all filters have this, it takes meds out of the water.

Okay , we don't have this and thank you

I was just wondering how many litres a shrimp needs if it was on its own and would it need an airpump and filter thanks
