I noticed about 3 weeks ago that there was some plaster dust in my cleaner bag. There are also a few spots where the plaster is pitted. Nothing major yet. I ordered a Taylor test kit and checked for CH. I guess itÃ¯Â¿Â½s really high since I never could get the water to turn blue. My TA is 100 and my PH is 7 which is a little low. I went ahead and drained about 75% of my water yesterday and refilled it to start over. If I get everything back in check will the plaster continue to be damaged? I can live with the way it is right now. ItÃ¯Â¿Â½s white so itÃ¯Â¿Â½s not noticeable unless you are looking for it. I can to work hard to convince my wife I wasnÃ¯Â¿Â½t crazy. She finally agreed there were a few rough spots.
