The equipment seemed easy enough to operate. They have the pump set on high, they said that would keep the pool cleaner. I thought the whole point of a two stage pump was to cut down on electric? I was also bummed to find out that I have to operate it with the breaker switch. I thought it was standard that they were on a timer. No big deal for this summer but I'll have to upgrade next year. He handed me a bottle of some.stuff called enzyme and told me.to put it once the pool is completely full, he said it helps to kill bacteria and viruses, I've never heard of it. Any thoughts on that? Thank you for the help.
