I just inherited a brand new canister filter. It's an Aquatop CF
-300 and exchanges 264 gals per hr. I have a 36 gal
planted tank. I know that there are additional media that you can place in the chambers and I was wondering if any type of additional media, like the biological ceramic cylinders or carbon are good or bad for the plants? My fish are all good and water parameters are perfect, so I'm not worried about them, but I don't want to deplete any nutrients from the water by using additional unnecessary filtration stuff.
Thanks for your help-D
