Re: Perimeter Stain
Do you know where the copper is coming from? The reason your stain came back after the stain treatment is because you didn't put in a sequestering agent to keep the metals in suspension. If the metals go back into the water, they need the sequestering agent to hold them in the water, if there isn't enough of it, the high chlorine levels will react with the metal and they will fall out of suspension and land on the surface of the pool. I asked where the metals came from, because copper is in a lot of the chemicals you buy at the pool store now - even in a lot of trchlor pucks. If you think the metals are coming in from your fill water, then you will always have to make sure that you have enough of a sequestering agent in your water. I hope this helps, feel free to ask any questions you may have.
