my current scrubber is 7"x12" and lit on one side by a 43watt cfl and the design allows light to flood into the sump area causing algae to grow in unwanted areas. my tank is a 45 gallon reef.
how much better would it be to make a screen that is 7"x10" but lit on both sides by 23 watt cfl's and in a box so no light goes into sump?
my goal is to purchase a sm100 or build something that is just as nice but i just don't have the money right now,,,i can only spend about $30.00 for now,,,,,my current scrubber cost me about $20.00 and was well worth it,,,thanks santa!
