I'm starting to get a lot blue-green gook in my 150. There's been a little patch on top of one of the tree stumps, but now I'm seeing it on the substrate. The water is very, very clean (no ammonia or nitrites, nitrates less than 5 ppm), but there s some organic debris on the bottom. Lights are on about 8-9 hours a day; can't remember exactly. Considerable tannins in the water. No other algae problems.
All the usual solutions are problematic. I don't want to add a power head because my angelfish wouldn't like it. Vacuuming isn't really an option with a soil under sand substrate, but I'd love a way to remove the mulm because it doesn't look that great. I'm afraid reducing the light any more will harm the plants, and I can't really get the water any cleaner than it is.
Any ideas, insight, wisdom, pagan algae removal ceremonies, or other assistance?
