Well I've been in testing HELL tonight trying to figure out which of my 3 test kits I should believe since they are all giving me different readings so I wanted to see what everyone is using and trusts?
For Phosphate, Calcium, and Alkalinity I've been using Hanna but started to wonder when my Calcium levels kept going up and up so I picked up a Red Sea test kit and the Calcium levels seemed a bit more real.
I have another post about my calcium nightmare here: http://www.socalireefs.com/forums/showthread.php?67477-What-causes-Calcium-to-go-up
I use salifert, I feel like they are a bit more user friendly than Red Sea. In the past I have used the API, Red Sea, and Hanna. I do use API for nitrates though.
Red sea for Calcium, Magnesium, and Alk. I think they are pretty easy to get use to and if you test often you'll know what you're doing. If you have any questions about how to work it, send me a pm and I'll guide you along.
The Hana Calcium test kit is super innacurate, unless they changed something these past few years. Look it up on RC. I use Hana for Alk and Phosphate and Salifert for Nitrate. I bought a Red Sea test kit, but it looked so complicated that I never used it.

Agreed that Hanna for Calcium is inaccurate. Red Sea for everything else. As mentioned earlier, seems difficult at first, but super easy once past the learning curve. There are a few YouTube videos on how to do the Red Sea tests that helped a lot..
