I am actually considering one as an addon but personally I am still running my standard equipment.
The screen will be 36"x9" with a mag 1800gph to power, my main problem is the lights, if I do 1wpg I will have 8x39w 312w T5ho that's just insane. I can do 4x39w for 156w or CFLs I suppose, what would you do, since I am running all my normal equipment the scrubber may not need to be as big.
