So I'm tired of guessing to see if my CO2 is really working and is at optimum level, so I have decided to buy a drop checker. Problem is which one? I have been looking at this one for the past couple days, but I heard that these kinds aren't very accurate. Can somebody help me in this area? By the way, I use a 3 liter bottle of DIY yeast CO2 in a 30 gallon tank and I use a ladder to diffuse it with a powerhead above to break down the leftover bubbles. I am also thinking of adding another 2 liter bottle of yeast mixtoure to my tank.

replace the following
1- with a good API ph reagent

Where can find this?

2- with a 4dkh solution

Do I make one on my own? If so, how do I do it?
Where can I find only a drop checker for cheaper? I can't find any locally.

I found a link here in AC how to make a 4dkh solution from basically nothing. Here it is. Will the color graphing system still work the same for this solution? The only way to buy just a drop checker is to buy the one I posted earlier, throw out the ph reagent and use the 4dkh solution.

I would think most all drop checkers will work the same since it's all the same method of trapping the gas.
