We have brown stains that extend from our jets down to to the bottom of the pool. We also have a step in the "deep" end with brown stains that run from the step to the bottom of the pool. There are also brown spots on the bottom of the pool that are likely caused by environmental dirt. There is no metal under the water line other then the pool light so I think it is just environmental dirt. It has been building up and getting darker over the last 6 months and I have not SLAM'd the pool during those 6 months. Does a SLAM sound like it is my best option to get rid of the brown? I hate to SLAM and not let the kids swim for a few days but it is at the action stage. Any help is appreciated!
