I have a 150G setup - upgraded from a 75g, running with an ATS for about 1 month. - moderately stocked
I have a horizontal screen 8" x 20" ~1200gph from return. Lit by 2x 23x CFL bulbs - 2300k and 5700k. I have lowered the light since from taking the picture.
In the first week or so I have been getting green hair algae to grow on the screen,
since then Cyano has taken over. I have also been growing some kind of sponge/ foam. No idea what it is.
What is considered good algae?
