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.

DIY CO2 will not produce enough CO2 for you to be at risk which is a good thing about DIY CO2. So with just the two sources, you should be just fine if you have enough plants. As with all things, you'll need to do some adjusting in the first few weeks but once you find your balance, you should't need to do much else to it other than refill your bottles when you need to ^_^

It usually isnt an issue, as lil said. But what i do is take off the lid or take the check valve off (keep the airline high, so no backflow), at night. So none go into the tank, just better for everything that way. But it usually needed.

For the day as long as you have enough plants and a filter you should be fine.

If you're worried about night (not really a huge issue, honestly) you can just keep an airstone or sponge filter on a timer that clicks on when your lights go off.

I've had two "if you have enough plants." So I'm going to ask if I have enough plants. I have 9 stems of ludwigai repens (will be 12 after next trimming) three stems of water wisteria (will be four) 7 stems of Bacopa caroliniana (although they are growing really slowly) one piece of amazon frogbit (I don't know how that is possible either) a tiny amazon sword (no root tabs so it is growing very slowly) and a merimo moss ball. This is in a standard 10 gallon tank.

Since it is always the next question on planted discussions, I am running two 11 watt 6500k GE CFLs. I am fertilizing slightly below recommended doses with an iron and potash fert.

Pandanke I'm keeping a bubbling filter going night and day. I realize that it will reduce my CO2 dissolved, but it will still be better than no CO2.

You don't really need CO2 at all for those plants honestly. They'd be fine low teching it.

I know, which was my initial setup idea, then I realized I had everything around to do a CO2 setup asked around a little and pretty much got the unanimous opinion that I didn't need to do CO2, but it would make the plants grow a little faster.

I'm good with them growing faster ;)

I think there are ways to adjust your formula so it produces less CO2 over more time. You might look into that.
