I found your article..... I had read this over 2 months ago, before I had
any BGA. I think I am too low on nitrates. I am going to test for this
....add what is needed, clean out as much as I can, clean filter, and do
blackout for 3 days.

I'm willing to bet that this is the case. IME, BGA has only appeared after a
long time with undetectable NO3. When you start adding KNO3, it should
eventually disappear with pruning and on its own, even if you don't do a
black-out. Generally speaking, running a high-light CO2-injected tank is
dangerous without adding extra NO3, K, etc. So you get rid of the BGA, then
some other algae, like BBA, will start spreading sooner or later if you
don't supply sufficient plant nutrients. I recommend ordering all your
chemicals at the same time from www.litemanu.com to save on shipping, as
well as getting a complete trace element mix like Seachem Flourish or
Tropica MasterGrow (those are the only two I'd use), or PMDD.
