Title: Hanna Phos Checker
Post by: SweetReefOH on May 17, 2019, 19:33:31

Has anyone had their low range phos checker go bad? I tested today and my first reading was .14 and I knew that couldn’t be, so I grabbed my other vial and did a quick test. It came back at .1. The next three quick tests came back .02. I have never had it read that wide of a range. So I have no clue what my PO4 is right now. Anyone experience this? And is the ultra low checker more reliable?

I’ve had no issues with mine. It could be a bad batch of reagent?

I tested the same vial/reagent, over and over. Got all kinds of crazy numbers.

Im not crazy about mine sometimes.  Really have to shake the vile up quite a bit to get all the powders mixed up and then contend with micro bubbles on the side of the vile. After shaking it up I will usually roll mine on its side to clear the bubbles and then let it set a bit before testing.
