I have an established 10 gallon tank I've just recently added plants to. The substrate is sand/gravel and since adding light for the plants the BGA algae, which I had before but was mostly under control, is gleefully spreading. It covers about 80% of the substrate within a few days of removing it.
I feel like I'm doing everything right but is there anything else that can be done to get rid of the BGA? I'm afraid a blackout would kill my plants and shrimp and I don't want to use antibiotics. Will it get better with time as the plants grow?
Thanks so much!
- The tank is lightly planted with a small amount of bacopa, pearlweed, javafern, and dwarf hygro.
- Lighting is a 23w 6500k cfl 6 hours per day on a timer. It was on for 8 but the BGA was even worse.
- I dose api leafzone 1x per week and flourish nitrogen as needed to keep nitrates 10-20 ppm; ammonia and nitrites are 0. No CO2.
- Residents are 2 very fat WC minnows and some ghost shrimp.
- I'm running an aquaclear 20 and a powerhead so lack of current isn't a problem.
- The sand isn't very deep 1/2 inch.
- The plants are doing great growing roots like crazy, I would like to have more plants but can't afford it right now.
