View Full Version : Random flow or Uni-directional

Which is better to have: random flow or a rolling circular flow? I am in the process of designing a 120 gallon mixed reef. I'm going to add a closed loop system using 4-way by oceans motions, with 2 returns on the bottom panel and 2 on the back panel. Anyone have any suggestions? Thanks
