Had my in-ground spa converted from a side drain (to holes on the side of the spa, connected to pipe running back to the pool) to a spillover. The water channel doesn't quite clear the coping stone between the spa and the pool. The channel was made from a man made concrete product. Any ideas on how to extend this channel, another 2 inches will do it. I am thinking a plate of galvinized steel, or a 2 inch piece of concrete cut at an angle and chemically adhered to the existing edge.
