This is probably has been discussed but my SO is asking me why are we buying so much bleach when to her Chlorine would end of costing the same amount and less time. Right now in the Central Valley we are averaging 90 degree plus days and I am going through bleach like no other. Please help me to explain why I am using this method. How much bleach do you guys normally burn through during the summer months? It seems like a gallon to a gallon and a 1/2 per week and with the cost of bleach rising I am starting to wonder that Chlorine would of been cheaper. I just checked today and I am down to 1 on my FC and it says to add about 3 qts of bleach. Also I am starting to worry when we leave in a couple of weeks for 4 days what is my pool going to look like.
