Aug 9, 2017 at 23:20 comment added Andrew Siemer Part of the circulation requirements is to ensure that the particulate matter that fish introduce into the system needs to run through various media types for extraction (either in the media itself or via swirl filter or similar). Aeration is another topic which can be done in so many ways. Bubblers, surface disruption, surface area (like a lake surface), etc.

May 20, 2016 at 1:58 comment added Russell McMahon @AndrewSiemer This is a 3 year old question of yours that I've updated my answer to. The changes were due to the suggestion that my assumed flow rate was too low by about a factor of 5. You may wish to check the answer if still of interest. Did you do anything like this? What pump power used?
May 20, 2016 at 1:56 comment added Russell McMahon @Johann Please see my update. Does that better match the need? Could aeration and somewhat reduced fluid flow meet the overall need at lower power levels?
