has anyone found that high co2 truly prevents its spread or growth?
The short answer is that high co2 in itself is not enough to stop BBA. I run very high co2, my ph is around 6 and my kh hovers between 2 and 2.5, so that is alot of co2. Everyday after 4pm my tank pearls like crazy, bubbles everywhere. If I acclimate fish too quickly in the afternoon they go right to the surface gasping. The funny thing is I was getting BBA on some slow growing foreground plants that didn't receive good light and on some driftwood that did receive good light, but I was also getting it on the inside of my ceramic diffusor where I would thing Co2 concentration would be extremely high.
My unscientific conclusion was that the BBA grows where there is an imbalance of light, organics and/or co2. |
