An apparatus and system are disclosed for a pool drain cover, the cover having a perforated ramp around its perimeter to which are attached a plurality of straight, horizontally disposed tubes, circumscribing channels with substantially continuous cross-sectional areas, each tube enclosing a channel extending the length of the tube of at least six inches. The cross-sectional area of the tubes is kept at a minimum and their number is increased by arranging the tubes in rows and columns or giving the tubes an elliptical cross-sectional area and arranging them in a single row, thereby reducing the tapering in the tubes. The cover may be segmented and may be of multiple shapes, including a circle.
