Thanks for all the positive comments!
I know this topic has been beaten to death, but any advice on how to battle this BBA before it gets a major foothold? It seems like a mix of staghorn / BBA. I'm doing H2O2 spot treatments once per day at 1ml/gal. CO2 running constantly, lighting reduced from 8 to 7 hours total.
I'm wondering if my dirt substrate is contributing to the algae? I've been doing trimming of some sort most weeks and the substrate gets disturbed, possibly releasing ammonia and other nasties. Would this feed BBA?
I don't really have any other algae problems so at least things aren't completely out of balance.
