2 gal of chlorine a week?

What's up with that??

Science. CYA binds most of the harsh component of the chlorine so the higher the CYA, the higher the FC can go while still being safe.

Another thing my pool is weird shape. progressivly deaper to the 8.5 deepend. how do i measure it and come up with accurate gallonage?

Take average measurements of the wall widths and start with a guesstimate. Dial it in with chemical additions such as how far the muriatic acid lowered the Ph, or that the CYA addition did what it was supposed to.

I grew up in the 80s and I have always heard and read everywhere even in my adulthood that you can't swim while you're shocking or suplerchlorinating a pool. cant swim if its over 5 ppm. and then I find this forum, and everyone says go right ahead even if it's 16 FC.
What's up with that??

The use of CYA.

Area of Polygon by Drawing is a neat website for plotting all those Freeform pools. The default shape on the graph is a pentagon but you can add points by pressing the up arrow and I got bored pressing it well after making a 100+ sided shape. If you zoom out on the graph you can make your Freeform pool shape with just a few measurements and round off all the extra points.

The area is shown up top at all times and multiply it by the average depth for cubic feet. Multiply that by 7.481 gallons per cf and it should be pretty accurate.
