Not to hijack this thread, but I've been battling bba if you have any tips for that.. I finally beat bga with strong use of Excel for a while. I've tried it with bba and while it turns red, it doesn't seem to die. Where possible, I spot treat on things I can remove or things that I can access during water changes... peroxide works well on those. When I replaced substrate in two tanks a month ago I scrubbed the wood and rocks and set it back. But it still makes an appearance in a few places. I have increased tank circulation and pushed lots of CO2 into the tanks. I fertilize EI and use RO water buffered to 4GH/4KH or so with magnesium sulfate, calcium chloride and baking soda. Thoughts?
