Hi Turbo, This is a question for the exploring options section or fit section. I have a fresh water tank and have signed up on the L2. I wondering if I needed to feed the fish more than 2 cubes per day could I just clean it more than once per week? I have 2 rams, 11 cories, 3 lemon tetras, 4 neons in about 75+ gallons. I know they will be getting bigger down the road. Any suggestions? Thanks in advanced.
