Help determining capacity

[Hgr1969]

I had an inground pool built in 2005. The plan measurements say 32’ length, 16’ width, with depth of 4’x6’x4’ (deeper in the middle) with a more shallow sun bathing area at one end. The plan says pool capacity is 12,840, but when I try to calculate, mine comes out much higher. I need to know approximate gallons to add chemicals correctly. What do you think?

Calculating a 4.5' average depth it's 17.2K and at a 5' depth 19.2K gallons.
Utilize chemical additions to dial in your water volume by testing, adding measured material and retesting.

Thank you!

A Chemical Way of Calculating Pool Volume

There is a way to use pool water chemistry to calculate pool water volume without using the traditional geometric calculations. The geometric formulas are fine for pools that are traditionally shaped. However, when pools do not fall into these convenient shapes, a chemical method can be used...

Whoa! I feel like I’m in chemistry school. Good info. Thank you!

I’m doing that test right now
