Aquarium Advice FINatic
Okay this is my first seriously planted tank I am attempting. I have two whisper ex HOB filters on my 56g column tank. One is a 70, other is a 30. Should I leave the carbon in or replace with something else? If so what. I don't know if the carbon will absorb all the fertilizer treatments. I use flourish excel every other day and flourish complete supplement once a week. I appreciate any advise as my LFS is not very useful for that. Thanks
