Hi All,
Looking for a suggestion from someone experienced with Hanna Marine Calcium Checker HI758 that knows how the test works.
Following this video --> (Min 2:50) the guy explains to use pure distilled water from an industrial brand to get a more accurate result instead of our home-made Rodi because it will always contains a bit of "calcium residue". He also mentioned he spoke with Hanna before made the video and they agreed on the fact that industrial rodi give a more accurate result. The lower the result is compared to our previous test (ofc tested in the same moment), the less calcium is present in the Rodi and therefore it should be more accurate.
Then, I went to the supermarket, bought a random pure distilled water and did the check; result is quite surprising tho.
CA with MY RODI: 460ppm
CA with industrial/supermarket RODI: 417ppm.
This made a substantial difference.
Now, I have a doubt and here's the question, maybe stupid:
Considering I am using my "home-made" RODI for my tank WC and ATO (the same I used for test 460ppm), should I consider my tank has a total calcium level of 460ppm or 417ppm?
Thank you a lot!
