I managed to clear up my long fight with BBA with phosphate remover, initial and daily Seachem Excel dosing, upping Co2 to drop checker nearly yellow but really observe make sure your fish are okay and making sure to do a weekly 45% water change but using a smaller siphon to really get all the detritus out of the plants and gaps also upping ferts . Also siamese algae eaters do a good job of clearing up but not solving the issue... lastly my surface agitation was a tad high which was gassing off a lot of Co2 and wasting my fire extinguisher lol but still need a good flow a fine balance is needed trial and error.
