So I screwed up. I opened the pool, added the stabilizer, but never lowered my alkalinity, and I let the ph drift high. Due to medical reasons we only used the pool 4 times all summer. I kept the chlorine at 1-3ppm, but I now have a thick layer of calcium buildup on the fiberglass pool walls. Would it be possible to fill the pool with soft water and keep the ph below 7 long enough to disolve the calcium then drain. Manually removing using power washer or sand blaster has been recommended, but beyond my ability right now. Any advise?
