In the TFP article START UP NEW PLASTER, it says no swimming during BREAK IN PERIOD. Never tells you how long the break in period is...after the pump is turned on, 3 days, one week, after pool chemistry is good? Help? Kids are dying to go in and it's been 4 days since the filter was turned on and we started brushing twice a day (been filled for a week.) When can we go in?
