ddier2020 - Thanks, neither can I!
Chris - Surge tanks could go up there, but I don't think I'm going to need that. Between the 2 waveboxes, closed loop, sump return on a WavySea, and chiller return, I don't think I'll lack much flow. Plus I have keyholes in the eurobrace so I can add Streams without much difficult. But that's a darn good thought, as I really like the idea of surge tanks. I've always been a bit concerned about the noise and salt creep they can create, though, have you had any experience with them?
