Hi Jesse! I'd stay away from the Hanna Ca checker for the time being. They're still working out all the kinks. I'm opting for a Salifert test kit until they sort their stuff up. I feel like I wasted a lot of money on an unfinished product, and even more reagent/packets to test different methods of testing they should have gotten straightened out before releasing it to the public. The Alk checker is golden though, but for me, the Ca is not worth the money at this point. Just a heads up and sorry if I went off on a tangent. Good luck finding everything else though! =]
Are you using the original test instructions? My readings always come up high no matter what. Tried everything on the RC thread without luck! Lemmie know...
i use red sea. all of em actually. i have been doin this for the last year or so i like em but whats funny i guess is that i dont really care for salifert. tomato tomatoe if it gets results you need use it. i also you hanna checker phos and alk and i love em. didnt buy cal because of previous notes
