When my test kits run out ill be switching to some of the hanna checkers. The calcium one gets mixed reviews. I just started using some of the red sea kits and i like them.

I have the Hanna Alk test and LOVE it. I plan on picking up the Calcium and Phos soon. It takes the subjective "is it closer to this color or that". It takes 3 minutes at most to do and I get a number take that number and times it by .056 and i have my DKH down to three decimal places. Can't get anymore accurate without a lab. I know they have a Nitrite one also that is harder to find but I will probably get that also. Not sure how useful it is though because it only checks Ultra Low Range. I only see one place selling it I know of so not sure it is useful for us. They also have an iodine one I will get if I ever start dosing that

I use Hanna for the Low Range Phosphates. Salifert Test kits for Alkalinity, Calcium and Magnesium. Easy to see the color changes. You get more tests out of the chemical ones and less with the digital instruments. Something to think about.
