Due to the new guidelines I re-worked my scrubber!
My new screen measures 7" horz. and 4.75" vert. =33.25 sq." It is lit on both sides by a 26watt outdoor CFL reflector flood 27000 K. My 1000GPH pump only has 12" of head and one 90 deg. fitting and is flowing like crazy! I plan on feeding 2-4 cubes per day on my 45 gallon mixed reef,,,,does this sound good? With my last screen I would always get DARK DARK green but almost black growth,,,I hope to now grow the lime green fluffy algae!
