Lifesaver Dec 26, 2017
I love this checker. After buying all sorts of phos test kits and being frustrated by either the jury-rig type of instructions and not feeling confident about the numbers, or not getting exact enough numbers, this was a god-send. Once you figure out how to use it, you'll never ever go back. The trick is in cutting the foil and opening it and "making" a crease for the powder to flow down. Also, I have it all ready before I even start so I don't get timed out. You can even fill 2 test bottles with water and have one all ready for that c2 stage. I couldn't survive without this as part of my maintenance schedule. And it is accurate.

Works like a charm Dec 19, 2017
Been using this checker for years now along side Red Sea phosphate test kit. Reads pretty accurate. Only downside is getting all of the powder out of the packet can be a pain in the butt sometimes

The only way to test phosphate Sep 14, 2017
The Hanna checker is the only phosphate test on the market that works. Titration tests are worthless, just spend a few extra bucks to know your parameters.
Won't go low enough Apr 14, 2016
Picked one of these up to try, it reads 0.00 on my tank water. My hope was to get some sort of reading above zero so I know it's working. Seems most people use HI-736 Phosphorus model. Anyone have high Phosphate and need a slightly used meter?
