I just ordered Hanna test kits for alkalinity, calcium, nitrate and phosphorus (not phosphate). Is anyone else using these? They appear simpler to use and maybe more accurate.

I like them. They've been reliable and easy for me. I bought a test kit for the Alk and it was dead on.

I'm just tired of trying to tell the difference between colors on a paper card. I never know if the printed colors are accurate, and whether I interpret the colors correctly.

I used them and went back to Salifert. Reagent was expensive and hard to find, at the time.

For a while the calcium was hard to find. I use my perk rewards to get the reagents from Amazon.

Don't know, use Salifert.

I still use Hanna for Alk but otherwise use Salifert for Ca and Mg. The color changes for those two are easy to see. :)

Easily ordered from Bulk Reef Supply, Amazon, any major supplier. About 20 bucks for Calcium 25 tests. Alk about 9 bucks for 25 plus. Well worth it to me for reliability and ease. I use Red Sea for magnesium.
