I have a fish only tank with live rock, and I upgraded from those junky float meters for salinity, to a 40 dollar refractometer. A couple months went buy and everything was measuring well, but then started getting calibration problems, and the test results would vary slightly. Measurements should be on the money I would imagine, but I Could not get them anymore.
I got mad and upset so I bought the HANNA SALINITY checker. Big waste of time and money.
I got the unit, and the next morning I did a bunch of different tests on the unit. Followed the instructions exactly, time and time again, I even tried varying the way I tested. I zeroed out the unit, used different test samples, used the same test samples, all brand new, rinsed out syringes, used distilled water, rinsed out the test well on the unit, and even used certified testing fluid.
After over a half hour of testing all these variables, in multiple ways, you would think that I would have at least one test reading that was the same???
All test results were different, and I don't mean by just one number. I got readings of 24 ppt, to 30, to 31, to 32, 33, 35, 40,41 and so on.....
Not impressed at all. Promptly packaged, and returned this unit to amazon.
A have 2 apex Jr. Running multiple probes, a huge battery backup setup using 4 deep cycle batteries, aqua illumination led units, 6 foot long tank in my basement, running through the wall into my Sump room.
And I still not have found a device that can measure the salt in my system properly, and consistently. Lol lol.
Do not buy this unit. I give it 0 stars, not 1 star.
Anybody who gives it 5 stars, should do multiple tests, the same way, back to back, and then text me telling me, telling me that it was just my unit that was faulty, or that it was the way that I conducted my tests.
I have thousands and thousands of dollars tied up in this marine tank. I take pride in it, and just want a simple way to measure salinity.
The quest is on now to buy a Top dollar, precision refractometer that NASA uses. Lol.
I never hardly write reviews for amazon purchases, and I buy a lot of stuff.
Do not buy this unit. Text me at 519-919-3833. I'm from Windsor, Ontario, Canada area.
Have a good day everyone.
