My husband and I just filled our pool and to our suprise, our water is extremely rusty. The water is a dark orange and we can't see the bottom. We have added the chlorine and shock treatment, but with this being our first pool, we are looking for some guidance. We would like to be able to learn to do this ourselves. My husband is planning on taking a water sample to our local pool/spa store in the morning, but we were are hoping for honest answers and not someone just looking to make money. We would greatly appreciate any help!
