BBA from my experience is caused by two factors that are present.

1. PH over 7
2. high phosphate and nitrate reading.

Drop the PH below 7 by adding more CO2 and Reduce phosphate in the water column. Keep Nitrate to 5-10ppm.

If you do this, I can tell you that your tank will be devoid of BBA. You will just get something else then.

Siamensis cats are really useful but you will need at least 5 or six.

Lots more plants also help. (stems)

Is the reason I need more stem plants, is because they remmove a lot of nutrients form the water collum?

Yes, in particular they will use up more phosphate (in small amounts)between all the plants and more nitrate.

I'm not an expert on this but I just got rid of those algae in my tank. It was brown black brush algae. It didn't look as bad as the picture but it's like brushy and hard to remove by hand algae. I think it was bba. I had this covering my crypts. I had those when my nitrate was at 3ppm and PO4 at 0.25, pH 6.9. I just started dosing npk 3 weeks ago in that tank and those algae's were gone in a week (nitrate 10ppm, PO4 0.75ppm, pH 6.9). I have no idea why they're gone nor why I had them in the first place :roll: . But I think getting the right level of npk must have something to do with the dissapearance.
