I hope someone can help me with this. Our pool has this awful barn-like/fish smell coming from it. I am a complete novice when it comes to pools but I'm willing to learn. Here is some background info: Our pool is an 18x48 above ground Intex pool. I used it last year and cleaned it out for this current summer. We brought it out about a month ago, cleaned it and filled it. We decided we were going to get the salt water system to go with it so we bought it about a week later. No chemicals were added to the pool prior so the water turned green. We installed the salt water system, and added salt. The manual states the salt water filter should run 4 hours a day and to use the boost option if there is heavy rain. Well since the pool was so green I ran it at the max 12 hours and constantly ran the boost option. Now the green has turned blue...although still a little cloudy but along with the cleaner looking water came that smell! It is so gross it smells like rotting something and anyone who goes in it smells from the water ( I know because I got in to vacuum it out) I don't know if its the salt water filter or the massive amount of rain we have been having? I don't know if maybe the boost affected it? Please tell me you have heard of this before and know a solution? I hate the smell and my family would love to actually use the pool! Please help. Thank you!
