Hanna checkers

Got my first hanna checker and I got the Alk Checker. I love this thing! I want to buy basically all of them now lol. I think I'll invest in the phosphate checker next
 
Deff a must have for serious reef keepers.I am thoroughly satisfied with the alk checker and the PO4 checker(the latest one) seems flawless and extremely accurate for my intended purposes.When you get your PO4 checker and become acquainted with your ranges,take close observation of color and PE with the different PO4 values you see and you will surely notice a trend with where your animals look there best in relation to PO4 levels.
 
I bought the alk, low range phos, and calcium checkers. These things are great! Only complaint is the reagent was bad on the alk. I guess I'm in the recall. But I did happen to order backup reagent right away. And the new stuff worked good. Alk came in at 8.7, calcium at 381, and low range phos at .03. Overall i am pleased with the meters.

Did you find the calcium checker to be long and drawn out? I've heard it wasnt worth buying.
