To filter or not to filter... that is the question
2.5g standard with 3 walls of xmas moss and carpet of dwarf baby tears (AKA the green room). Using it under my custom rimless 31.4g purely as a CPD fry raising tank.
I was going to just put in an air stone, but wondering if I should put in the Azoo Mignon filter 60.
Do I even need the filter?
