Hi!
I've been running an ATS for 4 months now. During this time it has only grown a yellow "gooey" algae and some brown/black types. No green algae on the screen so far.
The ATS has 18 1W LEDs on each side (15x red 660nm and 3x blue 460nm). The LEDs are on for 12 hours/day.
I've read that black/brown algae means high nutrients in the water and yellow algae means too much light. Since I have it both on my screen, I'm confused about how to correct it.
I clean the screen every week with a toothbrush, leaving very little algae remaining.
The aquarium display has green algae growing on the rocks and gravel and it doesn't seen to be reducing. I also have to clean the glass every other day.
Any thoughts about how to correct this?
