We put in the pool last summer. We have never had a pool. We tested the water ourselves with a Taylor 2500 and kept all levels where they were recommended. However we did not check the CH and that seems to have caused a scaling problem. We noticed it before season was over last summer, but could not get plaster people to look at it until recently. They came and suggested we drain and acid wash which they did last week. It removed some of the scale, but still not great. We refilled pool and pool company suggested we order a no drain kit. It has not arrived yet. Pool company told us to put some chlorine tabs in and to add nothing else until the no drain product is used. I have been reading this forum and others and am wondering if this is the way to go? Any suggestions?
