What kessil for a 45 gallon cube? I believe 24x24x18 or 20 I would love to run a halide but I can’t hang anything from the ceiling. Thanks for your time and consideration.
Brs measured the par at various heights for the 360 over a 24x24. I think 8-10" was the best height. I agree it depends on what corals you intend to grow and the effects of shadowing from your rock work. I would run 2. I have 5 over my 48x24x24.
