Today, we finally got city water. And I thought we would be home free with having discolored water but I was wrong. We had well water, so I always had to use a filter on the garden hose and it did it's job but I would still have to treat it with metal out. And that got rid of all the iron and our water looked the way it was supposed to. As I said, we got city water today and when the pool was half way full I walked outside to see it had a yellow tint to it. I didn't use the filter on the garden hose, I thought it would be okay without it. We have a saltwater system but we can't hook it up until Friday when the filter pump is delivered. We had to get a bigger one so the SWG would work. So, right now we are using the little filter pump that came with the pool which doesn't filter out that well at all. I have a 12x39 Intex metal frame pool by the way. I called the pool place and the guy told me to go ahead and shock it and add some chlorine to it and then when we hook up the SWG to let it run for 24 hours and see if the water clears up to the color its supposed to. He said it could just be minerals. He said it may not have iron in the water. I guess I would be able to tell by looking at the filter later today to see if there's rust that is caked to it. That's how it was when we had well water before adding the metal out chemical. He said for me to not add the metal out stuff until after we add the shock and salt and wait 24 hours.
I do not want to drain the pool. The last time we added shock (we had well water at that time) it clouded up our water so bad until we couldn't even see the bottom and the guy said that it would take several days but it never cleared up hardly at all. Maybe it was because we have a very sorry filter pump. So, I hope with the SWG and the new and bigger filter pump it will clear it up if the shock clouds the pool.
I know some pool places don't always know what they are talking about so I am here for a second opinion. I was wanting to know will the SWG help get the water back to it's normal color. And if there are other solutions to getting it back to a normal color without having to drain it. Thanks to anyone who can help!
