Right now my screen is 10x13, knitting canvas roughed up. I have a measured 300 gph flow hitting the scrubber, (335 would be better, 35x10,however that is all I can get out of this pump). I have a true 40 watt spiral cfl on each side, giving me 80 watts.
I see that home depot carries spiral cfl's with 60 true actual watts. Would that be better (120 combined watts) on my screen, or am I ok with the 40 watts. I am getting a darker algal growth, and my levels have gotten better. Just looking to get the most out of it.
