Well last year was my first and successfull (but cool) pool season, this year, with the economy still in the crapper, I'm on a mission to cut maintenance cost. what do all you do to reduce maintenace cost?
One bit of savings I may have found is a 50lb bag of food grade DE for the cost of a 25lb bag of pool grade. So the question is, can I even use food grade DE in my filter? Whats the difference.
