Trying to figure out the size my pool for chem balancing and more
Pool is roughly 20 years old
Approx measurements
Pool main body is 24x47 with beach entrance to 3ft to 7ft deep end - 30k gal?

Upper Pond water falls into main 33x15 2.5 feet deep - 5400 gal?

Hot Tub water falls into a bridge pond which falls into main pool. Hot Tub 8 x8 3ft deep - 500 gal?
Bridge water 12x11 2.5 feet deep - 2500 gal?

Left Zero Edge 16 x 2.5 2ft deep - 700gal?
Right Zero Edge 34 x 2.5 2ft deep - 1400gal?


Total volume 40,500?
Am I calculating vol correctly?
When I determine pool size for filter pump, solar panels, and chemicals do I only use main pool gal 30kgal?
I can’t seem to understand the pool size?
Thank you
Bill

Best thing you can do is start with your 40K. When you need to, test FC and pH. Make any adjustments the pool need for these using Pool Math (PoolMath).
Run the pump during additions, then test 30 minutes later. If your results are higher than expected, lower your pool volume by 1000 in pool math. If your results are lower than expected, raise your volume by 1000 in pool math. Wait until you need to adjust again and follow the process again.
When your results match expectations, that is your pool volume.

Ok this is great! I will use the app. And follow your instructions. Just what i needed.
Thank you!

Another way is to adjust what you think you need and then if it didn't hit the mark you were expecting you can change/ toggle the pool volume in poolmath back and forth to see which volume it is that matches the the value you currently got. That will be very close to the actual pool volume.
