I had to back track a little and put a slope on the flood trays so they would fill and drain at that right speed. What I didn't account for was just how high the flow rate of water entering the beds was. The water would drain at the proper rate but the flow rate across the beds was to low.
The original slope was changed from 1"of drop over the span of 36'
3" of drop over 36'.
