I'm just starting the threat is kind of a comparison from all the trials and tribulations we had from last year, I'm in day three of my slam and in 3 days it is changed as much as it took me to do in 4 weeks last year! I love tfp and the pool-aid tastes just as good as it did last year! My shipment of bleach is coming in tomorrow so hopefully I won't have to go and pick up any more from my local Walmart
