My 6 gallon aquarium has been overtaken by what I think is green hair algae. The tank has a ph of 7.6-7.8 and the Gh is very low the Kh is quite high. There is soil under the gravel substrate. I have 3 young blue dream shrimp in there I’m not sure if they’re eating the algae. I’ve tried turning the lights off for over 24 hours multiple times and still nothing I don’t know what else to do. Please help!
