Hi all,

I'm halfway through the process of cycling (fishless) my first pressurized CO2 tank. I bought the UP Aqua Drop Checker Solution a little while back thinking that all I had to do was put 5 drops of the solution into the drop checker and then put it into the tank. I now just realized that people add a 4 dKh water solution and a few drops of pH test solution into their drop checkers. My question is then: is the drop checker fluid that I bought purely a pH test solution or is it something different?

Also, if I make my own drop checker solution with DIY 4 dKh solution and pH test drops, does it matter how much of the solution and how many of the drops I put in the drop checker?
