Good to know that! My same experience! Have you tried to solve the problem is some way?

Melissa Morrison said:Interesting. When I moved my anubias from my high tech tank to my low tech tank, the BBA was already on the lowest under-leaves of the plant. For the most part, that is where it remained. It did spread across the lower leaves that it was already on, but did not effect the upper leaves that were closes to the intake tube where there should be more flow. Eventually, the lower leaves became carpeted with the stuff and I just ended up clipping them off. It also tried to spread to some of the older leaves of some amazon sword plants, so I just pulled them off when I saw it. Right now, there is no more sign of it. *crosses fingers*
What does DOC lowish mean?Likely just the very low CO2 levels.
BBA comes from streams and optimal CO2 seems to be 5-10ppm.
If it's lower, which is often the case in non CO2 tanks.............then it quickly dies.
While in a CO2 enriched tank, even after you correct the CO2 issue that was low or variable for a few days........then BBA will continue to live.
If the CO2 is stable and high, plan growth good, DOC lowish, then you never get any BBA bloom.
It's that transition range area that dogs people with BBA.
