The bottom used to be 6" off the water. When I switched to the EVC 10K lamps (they have almost 2X PAR of the Ushio on a M59 ballast) I raised it by 4" more inches. I like this better since I am now getting full coverage of 42" from to back.

Why did you switch to EVC 10K's and are you running an supplement Blue?
