hanna checker

Little story: Since my Hanna PO4 URL checker always turned on and appeared to work properly, I always assumed that, despite the glorious reviews, it probably wasn't that great. In fact, according the PO4 URL checker, both my display and my coral quarantine were always a random number between...

So I just bought a Hanna salinity checker for my tank. A little reason why I bought the checker. I travel a lot for work and so a lot of the time I’m not home to look after the tank. My family do a good job of the basics and then I do the water changes when I’m home. Recently they needed to do a...

If you own a stream deck or need a pretext to give the stream deck mobile app a try, you can try out my Hanna checker stream deck profile (attached zip file). I think the screenshot makes it self-explanatory, but let me know if you like the idea!

Hi all, my tank is 3 months old and I have made the decision to cycle some Caribsea life rock away from my main display which is eventually going to replace existing rock in my tank, as I believe my crazy high phosphate levels of 0.21ppm are being caused by leaching phosphate from the rock that...

I picked up one of the new Hanna HI783 Magnesium checkers when they dropped last week, and after one or two mulligans I got it working pretty well. A little more complex than the basic hanna tests (requires 2 reagents) but nothing too bad, especially vs the other titration mag methods. The...

Has anyone tried to use Hach (product nr 2459100) reagents for testing Potassium in a Hanna Checker with a 610nm led eg. the one for Alkalinity to test the Potassium level in a reef tank? If so did it work or not? If it worked could you please share the absorptionformula and the Hanna checker...

I got the magnesium checker about a week ago. It's very easy to use, comparable to the Alkalinity checker in terms of ease of use. There's only one extra liquid reagent to mix with the unreacted sample water, when concocting the "blank" cuvette for C1. When I first got it, I first checked its...

Hi. I wonder if there is a way to determine the clarity of Hanna Checker Cuvettes, so that one can determine if it is time to change them. I imagine that the checker itself should be able to give you a value for the cuvette with RO water that you can use to determine its "clarity". No...

Just got some new hanna checkers today and tested high range nitrate. The result was too high to read, and the instructions say to dilute it if that happens. I cut the sample in half and added more water, same result. After a second halving I got 52! This result seems ridiculous as I'd expect...

Hi Guys, I understand that hobby grade test kits are used more for reference and stability. I also understand that number chasing isn't always the best to do with our reef tanks. But I would like to share a story (photos included) and get your input. For years my hanna alk checker has been...

I made a large water change today, and thought'd it be "fun" to compare results between the new Hanna Nitrate High Range 782, and the old Low Range 781 using the dilution step. 781 Low Range diluted 782 High Range Percentual Difference Before Water Change 24,9 33 27,9% After Water Change...
