I've visited six flags a few times in my area. I've been to the water park. It has quite a huge pool. I imagine millions of gallons of water. One thing I notice is the water seems pretty highly chlorinated. You can stand next to the edge of the pool and small chlorine? The only time that ever happens with my personal pool is when I'm shocking it.... They don't indicate their FC levels anywhere, do they keep their water at shock levels? Also what type of pool equipment do they use. Do they use sand filters etc..... Do they use pure chlorine gas v.s. powdered/liquid forms?
