Eyeball fittings are designed to be aimed in the same direction, to create a circular flow pattern around the pool, or a slight surface ripple to aid in moving debris toward the skimmers, or can be aimed to deeper areas that need more circulation. Use smaller eyeball sizes closer to the pump, and larger diameter eyeballs further away, to balance flow among all wall returns.
