    Default Calcium tests

    I have used Salifert tests for calcium for some time. I recently decided to try a Tropic Marin kit. My tests differ by about 20 points - with the Tropic Marin test yielding the higher results.

    Do any of you have experience with these and have a feel for accuruacy and consistency?

    I use salifert and try to maintain my calcium around 450. Personally I would not worry about a 20 pt difference unless that 20pts puts your out of the range.

    I'm with Manjo on this. Always use salifert kits and try to maintain 440-450 Ca at all times.

    Thanks. I will probably go back to Salifert - perhaps before this kit is exhausted.

    FWIW - i ran the test today on the little nano in the office where the lights are brighter. The test requires that you add a solution until the blue color disappears. The very last bit of blue may difficult to discern (even with the separate vial of water used as a control) - especially if the light is not high. That could be accounting for the difference.

    I have read...somewhere-

    As soon as there is a color change from blue, that is where your calc is at. Even if it is still blueish.
