The back of my Cardiff 29G right now has 3 compartments. The first one is a skimmer which for the past two years has been doing jack squat and have been battling GHA and Cyano. I came across the idea of ATS and am loving it. Originally I was just going to remove the skimmer and then do a waterfall style skimmer that would hang in the top part of the compartment (9" wide x 6" tall), but now am thinking that I can basically do an upflow in the skimmer compartment. My question is, would it be better to use the Venturi pump instead of a standard air stone? I am thinking that venturi pump will distribute the bubbles more evenly and provide the same amount of O2.
I also plan on using LED through the back of the glass. For either design I was planning on 3 Deep REds and one Warm White (3Ws)
See diagrams. Thoughts?
