Can someone tell me what this stringy (algae?) is? It started about a month ago and has seem to have gotten worse. I clean the tank and scoop out the strings which breaks apart very easily but the next morning it comes back. What is it? and How do I get rid of it? 0 Nitrites 8.0 pH 80ppm Nitrate Alkalinity 120ppm 0 Ammonia 80.4 Temp. SG 1.028 I run a single AI Hydra LED light that is programmed to run at 60% power.
