I am going to used ada substrate, I have a Milwaukee c02 controler , I have A 250 MH 6700KV pfo retofit ,and two pc 65w 6500k pfo retofit. I did not like the pc to much the last time I had this sit up. I had a eheim 2215 canister filter on it. but I think I am going to drill the tank and put a sump in the basement and then plump the r/o unit into it . yes I fertilize but I did not know what i was going ,will need a lot of help in that area.
