It's a very pretty design, but with FC at 0 and CYA at 140, you'll probably need a slam in case algae's already got a foothold. Seems in the picture there is a slight green tint already. With 140ppm CYA and 22k gallons, a slam will be awfully expensive and difficult, with a FC slam level of 55, and currently at 0, you'd have to add 12 gallons of 10% chlorine just to get up to slam level. A partial drain and refill would be better to get your CYA down.
On the otherhand, if you're gonna replanted it, and I assume that pool would need to be empty for that, a drain and refill might be kinda pointless if it's gonna be drained in another week or 2.

By comparison, at 40ppm CYA, you'd target 16ppm FC to slam, needing just 3.5 jugs to get up to it at first and then add to maintain
