Thanks for the info, Hoppy! I can definitely vouch for 2 weeks or less being too early to start cleaning the glass. Also if you see green algae on the surface of plant leaves, don't clean it, leave it alone (I think it's also GDA even though it looks different than the glass one). I'm on my 3rd attempt now after the first 2 attempts failed (14 days and 10 days). The algae is thinner everytime, but it still came back after a few days. Will let it go for 3 weeks this time. |
