DIY CO2 Safety: Will a bubbler insure that I don't oversaturate CO2?
I'm fairly new to planted tanks, and am wanting to step it up a bit and play around with CO2 a bit more. I did some CO2 initially when I was first setting up my tank to get initial growth, but I didn't have livestock in the tank yet at that point. I now have ghost shrimp and a mystery snail, and will be adding fish including a Betta, Otos and Dwarf corys. I know that having high surface agitation, like what is caused by a bubbler reduces CO2 in the water, but am I still at a real risk of CO2 poisoning if I am running a bubbling sponge filter and a bubbling box filter?
My CO2 is a DIY 2 liter bottle with yeast and sugar, and my diffuser is a chopstick tip.
I'm really wanting this to be as inexpensive an operation as possible so would prefer not to have to get additional equipment, and when everything is looking good, I would prefer not to test parameters more than weekly.
