Hanna phosphate checker problems HI 713

[Quartapound]

Ready to throw this thing out the window.

Got it over a year ago tested my water a few times at that point and it read 0.00 every time.

I was skeptical as to the accuracy of the results.

Pulled it out again this morning and did another test and the same thing 0.00.

I am now out of reagent and don't want to waste money buying more if the dang thing doesn't work.

I can't believe my tank has phosphate levels that low, I haven't been doing much to control it

I know there was a recall on the reagent a while back but mine was not part of that lot number, and the expiry on them wasn't until January 2018.

I found myself wasting reagent often and having to start all over because it's such a pita to get all of the the reagent into the vile. (It's all but impossible going straight from the package into the vile, and only slightly easier using a folded piece of wax paper or a funnel.)

As funny as it sounds all I want is to see an actual number pop up other than 0.00, that way I'll know it's working at least.

Can I doctor the sample with soap or something to boost the levels and verify the dang thing's working?

This is what you need my friend. It will bring you piece of mind and assure you that your checker is ok . [emoji4]

They make standards for both phosphate checkers and for the Alkalinity checker also.
