    Estimating gallons

    Hi, I'm learning that the previous pool owner was either a liar or completely clueless. Pool light issues, depth of pool we were told about, etc.

    Now, I was told we have an 18k gallon pool. I'm thinking it is quite a bit less than that based on what I can figure using wiki.

    Free form pool
    22 ft long
    Widest width 14 ft
    Narrowest width 11 ft
    Shallow end 3 ft
    Deep end 6 ft
    7 ft wide jacuzzi(round)

    How many gallons do you think my pool really is( including jacuzzi)?

    Thanks friends

    Use pool calculator and break it down into sections of the pool at the time.

    Hmmm....
    Do I figure out average depth by adding shallow +deep and divide by 2 or am I way off? I was never good at geometry

    Pool is free-form. Measured in several areas the width. Widest point 14 ft. ave of the rest of the widths is 11ft.
