How much DIY CO2 for a 29 Gallon?
I have a 29 Gallon tank and am running 1 2 liter bottle of sugar and yeast into a glass diffuser into my tank. It runs out about every 2 weeks. I don't yet have the tools to check the CO2 concentration, but as my plants are not pearling, I suspect my levels are low. I have a moderately planted tank.
Would you suggest a second bottle? Is that too much for a 29 Gallon?
