Signed a contract Friday. They sent final plan Yesterday and started dig today. 2 skimmers. They moved one skimmer into the ledge area which has depth of 6"-9". The skimmer will be in 6" depth. Winds are generally Southeast in summer and Northwest in winter so the skimmers are placed correctly. Not sure why they moved to ledge from main pool area. PB said to keep ledge clean. Any problem with this set up? It seems strange to me. Will I get enough flow? New to pools but have been reading here for 4 months. Couldnt have done this without all your help.
