I'm trying to design a scrubber for my 800 gallon mixed reef system that's been running for about 2 months (4 fish + cleaning crew). I'm thinking about using a 48"x12"x18" sump that would house 3 rigid scrubber panels measuring 48"x10". Each panel would be 4" apart and fit lengthwise. I anticipate lighting it with T5 fixtures (4x48") on the sides and bottom, and one 400W MH (above). I would add it into the flow of the existing sump which produces about 4000 gal/hr.
Thoughts?
