Monitor Calcium/Magnesium HIGH Salinity (Salinity > 5 PPT) Test KIT (120 Tests) - Monitor Aquarium and aquaculture Water Quality

I wanted to see how well this kit might work to test wee for Ca and Mg and it worked perfectly. Use 5 milliliters (use a syringe) + 1 drop R1 + 1 drop R2 for Ca. There should be no color change on R1 (unless there is contamination from a previous test) and just cloudiness. Shake vigorously for at least 10 shots. Add 1 drop of R2 and it should be a rose color. Then titrate with T until there is no rose color and it will be a green color (versus blue due to wee). 6 drops would be ideal Calcium (not too much not to little).For Mg, in 5 mil add the scoop and again shake vigorously. It may appear green at first but you can beat it into an army brown color. Then titrate w/ T till all the brown shade is gone (green again - can be vivid green for true endpoint). Ideally it should take more drops for Mg endpoint than Ca endpoint. Good way to check Mg supplements are working (or if Ca is overwhelming).

Calcium test is dead on accurate. It's easy to titrate because the bottle design and large viles are better than any other test on the market. Results compare to ProLab with very low margin of error. Mag test is also accurate but titrating uses a lot of T fluid no different than other kits. Excellent value for the money.

I’m glad I took so much chemistry because it made this really easy. My mag was low so I added some, waited a day, it was still low, added some more, and test showed better results. Makes sense to me! Also like not having to use 2 separate test kits.

tested with name brand kits with same results ,like the fact it has a wider range, also like the dropper bottles instead of syringes , small spoon connected to lid means you'll never loose it.But most importantly it's accurate and being 2 into 1 it easier and half the cost seems to last a long time too at first I was skeptical never heard of it , now it would be painful to go back to the old routine with separate kits I highly recommend it.Dont let the generic no name scare you.

Compared to my other test kit which is almost expired this is only 5% different on the readings. I paid 4x the price for my other test kit.

It says "for fresh water" and won't mix with my saltwater despite the product claiming it is "suitable for salt water"

Overall I'm quite satisfied with this test kit

If you can't tell, the other reviews are so GENERIC! DON'T WASTE your time with this product!! Anyone can add drops and read color changes but when it comes to interpreting, yea there is a table provided but not shown in the pictures to calculate from mg/dL to parts per million but then up top it says it's high if greater than 5PPT (parts per trillion?). Oh, the table it's not really clear if it's parts per million, billion or trillion. Simply, there is no clear guide for interpretation as to what is safe, or concerning which makes it confusing, just get a test strip.
