Recently, there are these “deep green” in colour algae that coated over my hair glass and they are spreading very fast. I’ve tried changing 50% of water daily for 1 week already but it doesn’t seems to works. No matter how I tried to clear them they seem to come back within few days. Please help.

does the colour blue green describe the algae better?
does the algae from a 'sheet'?
think you have blue green algae, bga.
possible solutions are total blackout, manually removing it and balancing the nutrient in your tank. do a search in this forum on bga to find more information
