Hello, I was curious about adding chemicals. I am only running the water for an hour and then letting it rest for an hour, but I added just a touch of bleach so that the water didn't start to "slime" up over the next few days of filling. My question is when you completely refill your pool should you take it to shock level? And if so, how long should I keep it at shock level? Thanks in advance for everyones time and input.
