My first post in this great site may sound weird but I have a problem. We have an Intek 18' round above ground pool that is located about 10' from a steel building,I decided to make a homemade solar heater useing black irrigation tubing and garden hoses with a 1/2 hp submersible pump. Everything was working fine for about 3 weeks when I noticed a film of oil in the pool one evening, my wife and her friend were in the pool alot that day so I assumed it was tanning oil or sun screen that was in the water. The next day my wife put the pump into the pool and plugged it in but it didn't start pumping,you probably see where I'm going here. The pump's motor was oil encased and it started to leak into the pool. I ran the filter all day and the film is gone and the sides of the pool don't feel oily but is my water ruined and how about the sand in the filter? I just ordered a TF-100 kit and it will be here next week. What should my next step be?
