I'm a bit overwhelmed by the number of Hanna Checker for phosphate.
I've opened a poll to see which one you guys use.
Could someone correct me if my understanding of these three checkers is wrong? And maybe suggest which one I should get?
The HI774 sounds like the best choice for someone who wants to keep their tank with phosphate slightly above the Ultra Low mark (above 0.04 ppm).
From what I can tell, the release of the HI774 effectively made the HI736 obsolete, to the point where the real choice now is between the HI713 and the HI774?
I don't get tho why the HI774 has so few and mixed reviews on the BRS website
, even tho it sounds like it should be the checker that is best suited for the average reefer?

- HI713 Phosphate Low Range
- Not accurate at lower values that are attained by good Chaeto filtration and GFO.
- Test could read 0, when you actually do have enough phosphate. Not safe.
- Only buy if you plan on keeping your phosphate level higher than what is recommended for reef tanks (<0.2 ppm)
- Upper limit (2.5 ppm) is so high that it's actually a bit useless.
- HI736 Phosphorous Ultra Low Range
- Earlier "flawed" version of HI774
- Needs mathematical conversion to phosphate
- Timer is too strict
- Upper limit is too low (0.6 ppm)
- Earlier "flawed" version of HI774
- HI774 Phosphate Ultra low Range
- Later improved version of HI736
- No need for conversion
- Timer extended
- Upper limit extended (0.9 ppm)
- Weirdly, reviews on the BRS website are rather mixed? Why?
- Later improved version of HI736
