Im not sure what this is, although Im sure why I have it (forgot to soak my aquatic compost substrate).

Can someone confirm what this is? I have ALOT of it, everywhere. It sorta looks like BBA to me, although Im not sure.. its as resilliant as BBA thats for sure.

Full EI/CO2 and turned down light for now, Ive increased filtration ALOT and will do 2x weekly water changes.. any other ideas? Im assuming a blackout wont work on this if its BBA.

edit: I will obviously remove all visible signs on the next w/c. I purely wanted to see what it would grow like if I left it.

I don't know what it is officially, but I had it when my tank had a bad case of BBA and BGA. It behaved the same as BBA. Excel and manual removal got rid of it.
