I finally broke down and bought some Hanna checkers, I have been wanting them since we purchased the tank but never got them. So we finally bought the calcium, alkalinity, and phosphate checker. I absolutely love them, they've been pretty spot on compared to my Trident. I just say the calcium one is the most involved one bu isn't hard once you figure it out. Some people complain that it is hard to get the powder into the cuvette, but if you actually cut along the line like a "L" and fold the bottom tab under its very easy. Just take your time and be patient. It probably took me maybe 30-40minutes to do all of my testing and that includes honey time!!! I hope this helps anyone that is thinking about buying one, I wouldn't trade them for anything I hate the titration test!
