I was looking into updating my testing supplies and was wondering which hanna checkers you all actually found useful. How often do you use them etc?
Alk and PO4.
If you want I have I think 4 of the Hanna Checkers that were used very little, some have extra tests. I'll sell the lot for $100., they're practically new. It's Alk, PO4, Nitrites, and Calcium
Alk.
The Hi 736 Phosphorous, not so much any more. Too touchy/inconsistent.
