1. ## Calculating Gallons

Pool is 16'wide by 32'long rectangle. 5.5' deep in the middle sloping to 4.0' at the ends. Think volleyball pool configuration as slope up from middle is even on both ends. What gallonage do you calculate?

Thanks

Go to Pool Math (the link is above in the blue nav bar), scroll to the bottom, select Rectangular, enter your length and width, and estimate your average depth, and voila, gallonage!

After that, if you have a recommended test kit, you can carefully test your FC, pour a carefully measured dose of bleach into the pool, then within about 15 minutes test FC again. Put your old FC as "current", your new FC as "target", then play with Gallons until the amount of bleach you poured in comes up and presto - you have an extremely close estimate of your volume.

I would not call this a one and done. The strength of bleach can vary. Over time if you consistently are missing your targets for all chemicals, then you could adjust the volume.

That's an excellent point Jason, thanks for the clarification!

The question is volume. I'd always been thinking 15000 gallons but if you average middle and end depth you get 11000. A big difference.
