Hi everyone. I am having a pool built and I'd like some opinions on the number and locations of the returns and skimmers to make sure it's being done right. the pool is in ground, 35,000gal. Depth is 4' throughout. Standard chlorine with sand filter etc. It's basically a big rectangle with a 25 meter swim lane attached. Here is a diagram with the locations of skimmers and returns. Thanks for any advice/help. It's much appreciated.
