New to the group (also a new pool owner) and looking for some insight. We have an in ground 26000 liner pool with a sand filter and 1.5 hp pump.
My wife (God bless her) tried to surprise me and open the pool as I am out of town until tomorrow. She "shocked" the pool and took a sample to the pool store for lab levels. The woman helping her stated that we had no FC and a high TC of 3 or more and that we need to drain half of the pool and add new fresh water or buy approx. $200 dollars worth of chemicals. Again I am not home yet but this just didn't sound right and I told my wife to hold off until I get home in 2 days. If the FC is 0 and the TC is above 3 what are my options? and what would cause this? Thanks Aaron
