Total newb here. I bought a new home with a pool. The previous owner told me the pool held 40,000 gallons. I wanted to be sure of the volume so that I could make accurate chemical adjustments.
I used a couple of the pool volume calculators found on the web to find out if 40,000 gallons was even close to accurate. It didn't seem to be.
So, I set out to model the pool in Sketchup to get the true volume. Here's what I came up with:

I believe my 3d model to be very accurate. I took careful measurements of pool edges and depths and had no trouble transferring those into my Sketchup model.
Sketchup tells me that the volume of the object (which only represents the water contained in the pool) is 2998.4 cubic feet, which is about 22,429.2 gallons. THAT'S NEARLY HALF OF THE VOLUME THAT THE PREVIOUS OWNER THOUGHT IT TO BE!
My question to all you professionals:
Are there any gotchas in my approach to figuring the volume? Should I and how do I account for water in the filtration system? Am I being too anal about this?
