CO2/water Question

[corster]

If your PH is about 7.2 and GH is about 150-200 how long after you stop adding CO2 in the water does it remain in the water?

This would depend on several variables including: Tank Size, Amount of Surface Aggitation, Density and Type of Plants, Whether the Lights are On or Off, Initial CO2 Levels, etc. Best way to find out is to test levels CO2 levels before and after turning of the CO2.
