Ca/mg test kit


Recommended Posts

If anyone else is having a hard time with their water company while trying to find your taps calcium/magnesium ratio, I came across this while browsing Amazon this morning. I'm not sure if it's accurate or not, but the price was right so I took a gamble.

I'm not sure about the forums policy on outside links but if you search for the product 'B096V9J9JP' on the site mentioned above you'll find the product in question.

Keep us updated. If you can calibrate it to verify accuracy, that would be awesome.

If I can get any official word from the water company or the EPA I'll be sure to report. But at this point ill even be happy with inaccurate results that comfirm or dispute my thoughts. Which are High magnesium, low calcium on account of low KH.

Have you read your water quality report? Did it not say in there?

Yes, the information is very limited. An email to my local water company with the water system ID was never responded to. I stopped short of visiting my local water company office or making a phone call....

So, @Mmiller2001I finally got around to using that ca/mag test I ordered.

Funny story, I think the reason calcium and magnesium is absent from my local water report is because in my ttapwater they are virtually undetectable!!!

In my tank the calcium registered 60ppm which is comparable to the test strips which register -80ppm. Magnesium went from undetected to about 12ppm.

Question; how much Epson salts should I add to a 36gallon to bring the magnesium up to a suitable level? I would think this would also be a good way to calibrate the magnesium part of the test kit.

Depends on live stock requirements. I run 24ppm Ca and 8ppm Mg. That brings me to 5.2dGH in a 3:1 ratio.

12ppm Mg is enough for most plants.

Thanks! Good to know, from the ranges on the paperwork I thought 12ppm would be extremely low.

As a side note ill probably pickup a few more Monitor test kits along with maybe a Salifert. I like the ease of use compared to the old API kits, I also like that this kit takes away some of the guess work that the strips require.
