Drop Checker Solution
I am running DIY CO2 in a 10 gal plant growout tank, (no fish.) I want to test the amount of CO2 in the tank. After browsing the forum, I think I have the general idea how a drop checker works. My questions are these: 1.) What is a "4DKH" solution, and 2.) What is a PH test solution? And 3.) Where do I get them.
Finally, after reading about drop checkers it looks to me that the drop checker is not measuring the amount of CO2 in the water directly, but is testing the PH levels. Is this correct, or am I way off base? (As sometimes happens! I'm old, give me a break.)
