I have a 55 gal reef tank with 220 watts of T5 lighting 2 inches from the water level. Alot of precipatation builds on the current glass top and causes water spots that I know is blocking a certain amount of lumens from reaching the water. Do most people deal with continuously cleaning a glass top or have no top and deal with having to add alot more water due to the precipatation being able to escape the tank?
