Im pretty happy with my tank overall, the one thing that bugs me that i cant cure is i have a green dusty algae on the glass, when i clean the glass within the hour its back, i used to get this happen with my T5 unit, I've recently added Radions and I'm still getting it, my lights ramp up (using the AB+ schedule) for one hour, on for 8 hours, ramp down for 2 hours, nitrate at 2ppm and phosphate at 0.04, has anyone come across this before have any ideas, many thanks for reading
