Wavemakers and oscillators are water surge devices used in aquariums to produce the natural wave motion of the ocean. Simulating this movement promotes oxygenation, enhances the tank's environmental conditions through water circulation, and provides other benefits such as bringing food "to" corals and other sessile invertebrates. From simple directional water pumping powerheads, to programmable electronic units that can be timed at set entrevals, here are our top picks in wavemaking devices.

Expands custom options for outstanding water movement in aquariums of all sizes. Timer-controllable alternating or synchronous flow modes recreate natural wave or tidal effects. Adjustable flow rate fine-tunes water movement to satisfy the needs of your aquarium and its inhabitants. Use optional Night Mode Photo Sensor to automate wavemaker Night Mode. Koralia Controllable Pumps require Koralia Wavemaker Pump Controller for operation.

Each has adjustable dial(s) for quick and easy set-up. Also oxygenates water, stabilizes temperatures, moves nourishment around the aquarium, and flushes dead spots of detritus and accumulated waste. Duo controls 2 pumps; Quadra controls 4 pumps.

Plumbed inline, SCWD directs incoming water to two alternating outputs, switching automatically at a rate depending on incoming pressure. Install the 3/4" SCWD with 3/4" tubing and system pumps with flow rates from 50 to 1,400 gph. Install the NEW 1" SCWD with 1" tubing and pumps with flow rates from 500 to 3,500 gph.
