I understand that shocking a pool to get clear water to open a pool is the gold standard! At around $12 per application it seems pretty inexpensive, even if you have to do it twice.
My pool guy says shock is a waste of money, somehow? He suggests submerging a 50lb bucket of trichlor in the pool.
He says that in a week or two, you will have a clear pool - even with the pump off.
Anyone ever tried this approach? Would love to see what other posters found if they've tried it.
