Your Algae is not that bad. Also Algae will not harm your plant, just clog stuff and be annoying. Keep cleaning it with H202 or a safe cleaning alternative. I use physician 20 to clean my hydro. Good luck!

Dude you got no probs! You can get a lot of algea on the bottom of your tray. It's just a bitch to clean up after you harvest.
