Take a fresh sample of your water to the LFS and have them
test it for you. Bring along your kits if you like, so they
can show you how to get a reading.

Thanks Marc but these people are so incompetent that they should be bringing
their water to me to test. I have never had this problem before I started
using Southdown sand. I used to test regularly and had no problems with
RedSea's kit. I'm thinking of cutting the sample with 50% distilled water and
then just doubling my results.

You know, I am using Southdown also (just started a new tank). This
may be the reason I am getting high values as well. I've spoken with
others who use Oceanic salt and they don't have as high calcium as I
do. It may be the aragonite dissolving in the water to give high Ca?
