Hey Dan, are you still running 250w radiums with vho actinics?
Dan, you run halides. What temperature does your tank run at. Mine is somewhere in the 79 to 82 degrees give or take 1 deg. Do you have a chiller on your tank? I just wonder if this temp is affecting my PE. All parameters are on target. In my frag tank that is connected I have great PE.
Thanks Mark
