I traced the pic of your pool and it looks like about 15,000 gal, and mabye a shade under. The beach entry has almost no water and I took that into account. 1hp uprated or 3/4 hp full rated is all this pool should need unless there is some other waterfeatures that we don't know about.
Also, 2 skimmers is overkill for this pool. And if I may suggest, the beach entry should be a beach step instead.
