Moved to Vegas three years ago and have a 10,000 gallon plaster pool. Never had a pool before. Just switched from a pool service because I felt I could do better and avoid the strong chlorine smell. CYA was over 400. Draining the pool to start over, and will follow TFP using an initial 30ppm CYA dose and liquid sodium hypochlorite to maintain at 3ppm free chlorine. Phosphorous was 300ppb according to the pool store (who wanted to sell a lanthanum chemical to precipitate out), but I understand from TFP it is not an issue and I'm draining the pool anyway. With help from TFP, should be successful managing my own pool.
