My 40 gallon has hit the green water algae bloom phase and I'm tired of looking at green water! I know this is typical for a new tank so I accept that I have to just wait it out but is there a way to speed things up? Also, should I leave lights off until it clears up? I have 252 watts of light shining on it daily. My 75 gallon, I had a lot of green growing on the glass. I did a two day cover-up of the whole tank and when those two days went, the green glass was clear and I don't have to clean it near as often. I do get green glass on this 40 gallon but it's more of a light layer every two days. Should I try to cover the tank for a couple days and would that clear up the water?\n \nOne more thing. My back glass is totally covered in green algae. Should I try to scrape it clean or just let it go and it'll go through it's process?
