Re: PH controller vs. Drop Checker Well, I didn't expect such a debate from my question. Just so you all know I purchased a drop checker and installed it last week. It is working great. After installing it in my aquarium I could see that I didn't have enough CO2 so I turned my Ph controller down in small increments until the drop checker was showing a nice green color. So, in the showdown between Ph controller and drop checker I say BOTH win, drop checker shows me when I have just enough CO2 and the Ph controller holds it steady at that point. |
