My tf-100 test kit is on the way. Coping and tile are next on our new build pool. It will be rectangular 16x32 with quartzscape plaster. We have very soft water here. When we built the house I asked the water company if we needed a water softener and they laughed at me. Test strips on our tap water show no ch at all(will test with tf-100 as soon as it gets here). Will discuss with the builder, but would it be recommended to have water trucked in or is it possible to add calcium while filling with tap water? How long do I have to get the ch up before the soft water attacks our plaster?
Love the site! Thanks so much for your help!
