How to slow down Co2 mix? Too much Co2?
I setup a DIY yeast co2 a few days ago in a small 3g nano tank (Planted with HC & hairgrass, flourite black sub)
The water before the co2 had a very high PH (8.0+)
2 days after the co2 dosing, PH became extremely acidic..(under 6.0)! (referring to the PH/KH/Co2 chart, I think I am at 100ppm+ co2 level)
I run the Co2 in a 800ml bottle, with 1/4 spoon of yeast & 2 cups sugar. I am using a wood diffuser and I get about one bubble per second (without the diffuser).
I have 2 questions here:
1.) The tank is not stocked yet. Should I lower the Co2 dosing or do something about the PH? Can too acidic water / high Co2 content hurt the plants?
2.) Is there anyway I can slow down the Co2 mix / prolong its life? (i.e. add 1/8 spoon yeast? or add baking soda,...etc)
