Drained and refilled pool with 7 month old dark gray plaster (colorscapes).
I have added liquid chlorine, CYA and MA. These are my test results:
I am concerned as to how to add calcium hardness increaser without etching plaster finish.
Can i dilute CH increaser in bucket of warm water before adding to pool? CH increaser instructions state just to broadcast in pool with pump running without premixing in bucket of water.
Also should PH be a certain level before doing this?
