Rapid film algae growth

Anything change in your temp or lighting I was having heat problems and mixed with my lights and house temp and was getting same thing , I cut my halides back slightly and got a cooler temp going and it's helped, good luck on your battle

Doug, I don't think you've done enough water changes. Try a few more. JK
Seriously though, if it's not nutrients then try less light for fewer hours. It certainly can't hurt. Any other types of micro algae showing up?
