I'm pretty sure I'm at the proper gph for the tank hitting right on the 3-5x the volume. I don't have an issue slowing down the drain. It just seems the valves all have to be tweaked so slightly to maintain the balance between the drain and the pump that if anything got in the way or changed we could have a huge mess on our hands. I did jump the pipe diameter from 3/4" to 1" just below where the herbie drain comes together. Is that maybe causing an extra hard pull and creating problems? Should I have left it all 3/4" top to bottom on the drain?
