cost

Yeah, I use the 5 gallon carboys. I get them from a pool store that uses the square ones, not the round ones. I paid $6 each for the carboys about 5 or 6 years ago and now just pay for the refills at about $17/per.

Is that $17/Gallon or $17/Refill (5-gallon)?

EDIT by Watermom: I trimmed the quote to include the relevant part.

Carl - where do you get the chlorine refills?
