I have an infinity edge pool with 76' of vanishing edge and I do not think the current over flow pump (180gpm) is able to keep up with the overflow. There are sections of the vanishing edge where the water does not come over. We have re-tiled some areas and they are fixed but then another area has the same problem where the water does not come over. I'm thinking that if I had a larger pump, more water would go over. Any thoughts?
