Hey all,

Sooo I am clearly doing something wrong. But have no idea which part I am failing at. Not new to the hobby but still totally clueless on this one. So I have been using ESV salt which I mix up in a brute trash can in my garage. I mixed 2 batches from the mix. The first batch was 25 gallons worth and the second was 20 gallons worth. However, I got a new Hanna checker and tested the new water (note the old water was not tested) and the dKH is coming up 16.3!! I didn't even think saltwater could hold that dKH without just precipitating out. Salinity is 34. Refractometer calibrated and it matches the 34 in my tank.

**for those not familiar ESVs salt comes in individual components so that nothing settles out. In fact accuracy from batch to batch is EXACTLY why I made the switch.

I have measured out the remaining mix of a 50 gallon salt mix. They are all relatively close. I have nearly EXACTLY enough of each left over component to make just under 2 more gallons of water.... 1.7 gallons, 1.95 gallons, 1.8 gallons etc. So it is highly unlikely heavily overdosed on the component B or anything.

I have also run multiple multiple tests with the Hanna Checker and they almost always come up 16.3. When I test my tank I get readings around 10 -which seems fairly accurate for where I would have assumed I would have been. I also have floaties in my hanna checker reagent. I would blame them but the readings have been soooo crazy consistent.

What am I missing???

Floaties in Hanna reagent normal?

Yes. I was going to say. Sometimes I suck up these "floaties" from the bottom of the reagent bottle and I get crazy readings like those you are seeing. Try measuring grabbing from the top of reagent bottle where its only liquid. If still that high the checker might be damaged. Or I should say probability is broken is maybe higher than you actually having 16+dkh
 
Right? The odd thing is that my tank measures around 10 dKH (consistently) which leads me to believe that the test is correct. The number displayed on the checker is dKH and not something I have to convert correct?

No you don't convert with the hanna "dKH" checker

Pick up an API or Salifert kit and do a crosscheck
 
I'm pulling a 6.1 reading tonight twice on the Hanna dkh tester. This is concerning...

You could buy an API test kit for a crosscheck

or the calibration - check - vial package.

I'd go with API alk kit, but it's your call.
