I had to empty the pool as it was so out of balance that it would not behave and it became a chemical nightmare. I am learning who to trust and who not to trust when it comes to pool chemicals. They all tell the truth but if you are like me you forget to read the subtle differences. They "All they can do" or "We can-do it all in a package" are my worst enemies as they add what they want and it causes chaos in whatever I do. The pool is about empty and I am going to fill it with water now.
