….. my local fish store calls the water liquid rock :roll:
I thought that term was reserved for our water here in central Ohio. :lol:
Going back to when Mr. U Tin Win of the Hein Aquarium visited the site where they were collecting CPD’s, the water tested at a conductivity of 250 microS/cm which is typically classified as hard water.
250 microS/cm * .64 = roughly 160 ppm
160 ppm / 17.86 = 8.95 dGH
In most water hardness charts;
51 – 120 ppm = moderately hard water
120 – 256 ppm = hard water
256 – 425 ppm = very hard water
> 425 ppm = rock hard water
