My pool was just finished yesterday and we have been filling the pool with three hoses. I am wondering when I should start filling the spa. The spa spills over into the shallow end of the pool. The water has just reached the shallow end. He left me info on start up, chemicals and cleaning the filter, but told me over the phone if it takes too long I should spray the plaster with a hose so it stays moist. I am not sure about this, because wouldn't leave marks where the hose spray is settling. I had the pool re plastered with ultra brite marble finish.
