Have you thought about going with a Herbie system instead?
two bulkheads in the same overflow, definitely consider a Herbie. Personally been in front of 2 high flow (1900 and 2000ggph) systems and have to say truly silent. Here's a drawing from rban on RC that shows the idea. About the only changes to it would be suggest a gate valve (easier to adjust) and just leave the secondary dry.
