For my future pool build (see signature), I'm considering going with a venturi type skimmer (example shown here), but from what I can tell these are fairly new and not many folks have them. I understand the concept (increased suction using a pool return), and I understand what a venturi is and how it works. But can anyone out there with real world experience using one of these shed any light on their personal thoughts, especially if there are any reasons I may not want to use one (other than the initial higher cost of purchase)? I plan to have 2 skimmers and 6 or 7 returns, as shown in my design here. Thanks!
