FAQ
What makes a wavemaker “reef-safe”? Reef-safe wavemakers use non-corrosive materials like titanium, ceramic, or plastic in all water-contact parts. They avoid copper, brass, or exposed magnets that can leach toxins into the water and harm corals or invertebrates.
Can I use a wavemaker in a glass tank with a plastic rim? Yes, but ensure the magnetic mount is rated for the glass thickness plus rim depth. Most mounts work on glass up to 12–20mm thick, but thick rims may require a spacer or alternative mounting method.
How do I prevent wavemaker noise over time? Noise often comes from impeller imbalance or air trapped in the pump. Clean the impeller monthly with a soft brush, and ensure the pump is fully submerged. Replace ceramic shafts annually if you notice vibration.
Do wavemakers affect tank temperature? DC wavemakers generate minimal heat (5–15 watts), but submersible pumps can raise water temperature by 1–2°F in small tanks. External pumps like the EcoTech VorTech MP40mQD eliminate this issue entirely.
What is the best placement for a wavemaker in a reef tank? Place the wavemaker on the opposite side of the tank from the return pump to create a circular flow pattern. For SPS corals, aim the flow across the rock structure to prevent dead spots. Use two wavemakers for tanks over 100 gallons for random flow.
How often should I replace wavemaker parts? Replace the ceramic shaft and bearings every 12–18 months to maintain flow and silence. Clean the impeller and intake grille monthly to prevent algae buildup. Magnetic mounts should be inspected annually for corrosion.
