I have read up on mixing the chemicals, since the explosion, and I know now what I did was very wrong and that God was watching over me. I will never do it again. I have also found the answer to my question about adding the shock to the skimmer with tablets in the Automatic chlorine feeder. (Don't) What I have not learned, and still need to know is how to dispose of the bucket that still has chemicals in it. I'm not into using the broom handle method, I need another option. Below is the chemicals that I am currently using. The Trichloro-s-triazinetrione tablets in the Automatic Chlorine Feeder and I normally add 3lbs of Refresh to a 25lb bucket full of water, stir until mostly dissolved, and slowly pour into strainer while pump is running. This is the way the pool store told me to use it for a vinyl liner.
Last Friday evening, we were going to shock the pool, and I only had 2 lbs of Refresh, I had some Members Mark quick acting shock that we had quit using because it didn't do a good job, so I added a 1 lb bag of this to the bucket. I stirred it very little, and brought the bucket to the side of the pool and left it there for a few minutes while I cleaned the opposite skimmer. That is when it started exploding.
It has been sitting outside in the sun since Friday, that is 4 days. Will is still be volatile? I have been afraid to touch it. I have been told by the pool supply stores not to pour the granules straight into the vinyl liner pool. I am retired, and inherited the pool with the purchase of my home 2 years ago, the pool came with no instruction manual.
