Low flow refers to a tank that may have no additional circulation or flow creating mechanisms beyond a return pump. The corals below need only low water flow
Low flow refers to a tank that may have no additional circulation or flow creating mechanisms beyond a return pump. Medium flow is created with the addition of powerhead(s), closed loop system(s), and wavemaker(s). Intermittent flow is created with wavemakers, “smart” powerheads, and aquarium controllers that can create an intermittent current. The corals below need low-medium intermittent water flow

Medium flow is created with the addition of powerhead(s), closed loop system(s), and wavemaker(s). Strong flow is created with the addition of more powerful powerheads, closed loop systems with more powerful pumps, and wavemakers. Intermittent flow is created with wavemakers, “smart” powerheads, and aquarium controllers that can create an intermittent current. The corals below need medium to strong intermittent water flow
