My plaster (Quartz) pool was completed this spring. The last 2 tests I have done for CH are showing very little calcium so I am going to go buy some today. I just want to make sure that this is all normal. When the pool was started the CH was very high (600) and I have never added anything to it. I learned it was due to the new plaster and that it would balance as the plaster aged. SO has it now just reached the age that it is not adding calcium to the water any more? I just want make sure I am on the right track and not missing anything!!
Here are full numbers from today...
FC 5 (raising to 7)
CH did not get any red on test
