Hi, i have a question. I use flourish excel for C02 for my plants. I want to know if i add a air stone, will this take the C02 away? Or nothings going to happen?
It will cause the CO2 to be given off because of the surface turbulence. The less the surface is disturbed the better. The fact that the CO2 is dissolved is better, but once you make surface turbulence the CO2 will start the go.
Surface agitation does not affect Excel in the way that it affects gaseous CO2 supplementation. Not sure where I read that, may have actually been on Seachem's website.
