I don't use them, but I am interested, I will probably wait for the new version (Flex Series). I do have a question for VCA or whoever can answer it, what happens when you go above the suggested optimal flow? I run two 3/4" returns on a 75g tank coming off from a COR pump (2000gph, but of course, there's some head pressure holding back the maximum flow). Both outlets are fitted with Loc-Lines.
Or...if I dial back my COR, are there any noticeable signs that you are within suggested optimal flow range?
