I am newbie and just set up my planted aquarium for 1 week. My tank is 36x15x20 with eheim 2273, CO2 2 drop/second, and Finex Ray2 led light. Both light and CO2 are on 12 hrs/day. After water change, the test was done with GH 120ppm, KH 120ppm, PH 7.5, No2 0.5, No3 20. After 1 week, I saw algae begin on ground and on top of baby tear carpet per pictures attached. I think this is hair algae but I am not sure. Could any of you please let me know what should I do to stop this algae and help my baby tear growing better. Thanks a lot for any help from you.
