From res is a 3/4 barbed bulkhead to pump, from pump is 3/4 manifold to crosses downsized to 1/2 going to each waterfall. Done deal, plenty of flow and water levels never change due to the 3inch return lines, even when filled with roots. My bucket lids can open 1/3 of the way so I can pull roots out of return lines easily incase I need to.
