    Hi everyone,
    is a pH of 7.6-7.8 too high for CPD’s to breed in?

    thanks

    Hi Austin, welcome to the forum!

    Your pH is getting up there, but I don’t believe it’s too high. When Mr. U Tin Win visited the site where CPD’s were originally discovered, he measured the water at pH of 7.3

    Keep your water temperatures in the lower 70’s F and you should be fine.

    oh by the way, is water hardness significant? 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
