I have had my test kit about 5 weeks maybe, and I have almost gotten everything where it needs to be, except the CH. When I do this test, it does not turn red, but pink. I continued on with the test, and according to it, my CH is somewhere around 900-920. Doesn't that sound extremely high? When i empty out the pool cleaner, i dump the sand into a bucket. After a day, the sand has dried and turned white. Am I seeing a really large amount of calcium or is this normal with new plaster and swg? Thanks again for everyones answers.
