I'm having a hard time with Hair algae and some dark green algae that is trying to cover some Java Moss. I've been working on the algae for at least four weeks now. Today I pulled down shades at the other end of the room, about 15 or 20 feet away, just in case - it's a south-facing window.
I put 13w Compact Fluorescents in, not too long ago, and replaced them with 10s when it was apparent the algae wasn't going away.
Many weeks ago I accidentally started dosiing Flourish Comp at something like 150%. I was doing 25% water changes, but I don't know if it was enough to keep the Flourish Comp from building up. I've done six 50% water changes since I figured out I was overdosing about three weeks ago. I'm also dosing Flourish Comprehensive at the correct dose according to my bottle, and some of the plants are showing some growth now. Is that enough?
Anyway, the Hair algae seems a little less voracious but still hanging in there. Any ideas about which or both things are causing the Hair algae and suggestions about what I can do?
Thanks for the help.
