I have a 3 month old algae scrubber that quickly grows a thick, dark, dense layer of algae on the screen. I clean it weekly leaving some on there to keep it seeded and not rinsing with water. I just allow the free bits of algae to flow into the DT as a snack. Screen is about 8"x8"
I currently have a par 38 spotlight led, one 1600 lumen (100 w equiv.) led standard bulb, and 2 2700k 23w CFL bulbs on the scrubber on a 17 hour light schedule. Pump is a large 2300 gph aqueon dialed all the way back plus an inline ball valve on the plumbing slight closed. Water currently streams swiftly but smoothly across entire screen.
I am still unable to get turf algae, or lighter green algae despite my best attempts. I feed an entire cube of food a day plus small treats/snacks and about 4 sq. inches of nori.
Phosphates are about .10 ppm and nitrates are just above 4 ppm tested using the red sea test kit. I currently also have algae in the display tank on the tops of about half my rocks. I know that I could possibly have a couple rocks leaching phosphates as well but levels seem to be under control because they are constant every time I check.
What improvements and changes do I need to make?? And Thank You in advance
