Depth(ft)x 7.5 will give you a rough estimate of your pond volume.Mon, 28 May 2007 04:49:39 GMTjackN.http://forum.petstore.com/Topic68396-30-1.aspxSo I finally removed the old pre-fab rigid liners, dug out the hole to approx 450-500 gallons and bought the liner and some rocks, everything is ready to go. I really wanted to rent or borrow an inline water meter that could be attached to a garden hose so I'd know how much water it holds. That never happened and I doubt I'll come up with one on Mamorial Day. Are there any tricks for estimating the volume? Maybe I could time how long it takes to fill a 20 gallon tank and then time the pond fill? Any better ideas? TIA, - DSun, 27 May 2007 15:54:48 GMTDavid M
