Gas removal - how long should it take?
I am needing to do a quick assessment of my true co2 levels in my tank.
About 2 hours ago I took out about 1/2 gallon of water and have 2 large airstones aerating the water to push out the gases. from here I can tell how much the Peat moss (have tons of it as a substrate) is messing up my co2 calc.
question is, how many hours in to the aeration should I wait to do/trust any pH testing? With my tap water it takes about 3 hours to get to its true pH doing this. Don't know if co2 sticks around longer for any reasons though.
