My system includes a wet-dry cpr sump with live rock replacing the bio-balls. I also have a refugium connected. I use 0 mechanical and 0 chemical filtration. Being that the chamber you are thinking of using(live rock instead of bio-balls) is an instsnt fuge/mini-sump. I'd recommend a skimmer with the set-up. So, basically the only filtration my system has is macro, sand, live rock and skimmer. Phosphates and nitrates have never been a glimmer of an issue. Will this chamber get lighting for macro? _________  |
