More on the ATS set up
3 screens of 46.5" x 10" which gives 3 x 465sqI = 1395sqI of screen
each screen will be fed with a 6000Lph (1585Gph) pump
on the drawings you see the light set up pretty clear I guess with 2 stations of 7 T5 of 54W and the 2 outside light stations with 5 T5 of 54W each.
This giving a light capacity of 2 x 7 x 54W + 2 x 5 x 54W = 756W + 540W = 1296W Total light
again water will be fed through the sump and will drain through 2 2" drain pipes into the Refugium.
This setup was co designed with the re-inventor of the Algae scrubber system Mister SantaMonica.
