Hi there,
I haven't logged in here since mid-February. I just wanted to note that I'm winning the war on the brush algae. I tried many things since February short of beginning fresh. It was Flourish Excel that helped the most.
I wrote a long-winded post about it in my blog:
Controlling Brush Algae (Part 2) There's nothing new in that post, just personal observations and a few pictures.
If I'm not mistaken, it was here that I found the idea of using Excel against this algae.
Thanks for all your suggestions.
