The literature for my pool lists it as 18K gallons, but we were told by the builder that that measurement is when the pool is filled to the very top (which it never is). Do I use 18K gallons for the purposes of pool chemistry? If not, how do I know how many gallons to use? If it helps, when the pool was filled for the first time, they said it took exactly two 7K gallon truckfuls, but I don't know how accurate that is.
