I did a test today to see what the difference in PAR was for my tank from screen top on to screen top off. I used a Seneye and the results are shown in the screenshots. The Seneye was kept in the same position on the sand about center tank. For the screen top on I passed the Seneye cord through the feed door.
PAR Reduction: 20%
PUR Reduction: 2-3%
Screen Top: Black Mesh 1/4"
Light: GHL Mitras LX7, 10" off water and 9" off screen top
Tank: 24" (L) 18" (W) 18" (D)
I changed the screen mesh from clear to black last night. Wish I had taken measurements with the clear as a comparison.
The black makes the overall appearance of the tank look better, a lot less glare on top and I also think the clear was contributing to excess light scatter in the tank.
