Do you run the reflectors over the Penn State tank without glass?
How high off the water are the bottom of the reflectors?
If you run without glass at this distance to the water have you lost any reflectivity due to salt spray eventually dulling the reflective surfaces even with routine cleaning?
Thanks again,

Yes, they are without the glass. Lumenarc did not have the glass when we got these.
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.
The refletor does get salt spray, but so far they have been easy to clean. I have not had the kind of pitting that I had in the past with other reflectors. They must have a better material. They still are pretty shiny after 5 years of use.
