Can someone tell me there is a rule about using glass on aquariums with lights? I understand from mixed reviews, glass cut light spectrum/ lumens required for corals and inverts to fully survive.
I can understand in nature, we don't see a sheet of glass over the natural reef bed. I can understand the elimination of glass top and replacing with egg crate. But how do you solve a problem with a piece of glass being used as a support for prevention of glass bowing on the side?
ex. 6 feet long tank, 2 feet of open space for glass top on ends, 2 feet of permantly attached glass in middle.
Three 175 watt MH
Or,
Should I use two 250 watt MH?
