dont use excel, it can kill off your other plants if you overdose. just do a weekly water change and siphon out the cyano. how long have you had it for? it usually sticks around for a month or two before something replaces it.
With excel I use 1 to2 drop max everyday or 2. Except frogbit every other plant is thriving.. cyno has been there in the substrate, half of my substrate has been reduced by siphoning lol..there is no other algae except that.
@dreamchic go for it n good luck, don't forget to share you're bowl pics
