I'm hoping someone can tell me how to get what looks like rust spots inside my fiberglass pool also my tiles that I had put on the pool are also stained. I just had this pool put in October 2007. It is a saltwater pool and I opened the pool up on Thursday it was green now it is clear but I see rust spots. I took the water to be tested at Leslie Pools here are the test results:
The test results are from Friday since then I've added a gallon of bleach a day to this pool
Water PH 8.1
Total Alkalinity: 120
Calcium Hardness: 310
Total Dissolved Solids 3000
If someone can give me some idea how to get the stains out I would appreciate it.
