Best Aquarium Wavemakers and Powerheads for Reef Tanks (2026)

JEREPET's wavemaker is a 2.7 by 2.7 by 2.2 inch, 12 W DC pump with a controller and digital display, rated up to 2,100 gallons per hour for 50 to 100 gallon tanks, according to its listing. Modes include pulse wave, steady stream and a 10 minute feed pause, with master and slave control for two pumps. It mounts magnetically on glass up to 12 mm (half an inch) and comes with a foam guard.

Controllability matters on a reef. Reef Builders notes that good wavemakers can be turned up and down and programmed to create different flow patterns, which avoids the steady blast that can damage soft tissue.

Sicce's XStream 5000 is a magnetic flow pump rated at 1,320 gallons per hour for tanks up to 130 gallons, made in Italy, with a 360-degree adjustable mount, according to its listing. It has no controller, so it gives steady flow. Pair two, aimed to cross, for more varied current, or use one alongside a controllable pump.

Sicce's own page lists the XStream 5000 at 5,000 liters per hour, the same 1,320 GPH, and 6 W for its 230 V European version. Its magnet holds on glass up to 20 mm (0.79 inch), the thickest rating of any pump on this page, and a rubber layer on the holder damps vibration. Inside are a stainless steel AISI 316 shaft, ceramic bearings and a self-cleaning impeller, and a spiral cover guards the cord against chewing. The same body comes in 3,500, 6,500 and 8,000 L/h sizes.

Hydor's Koralia Nano 425 is a 4.5 W pump (Hydor's figure; the listing says 4 W) rated at 425 gallons per hour, ideal for freshwater tanks of 28 to 50 gallons and saltwater tanks of 15 to 30 gallons, according to its listing. It measures 2.4 inches, mounts with a vibration-absorbing magnet and suction cup on glass up to half an inch (per the listing), and includes a cable protector. Hydor also sells 240 and 565 GPH versions.

Hydor's own product page lists the Koralia Nano by liters per hour, and its 1,600 L/h size works out to 423 GPH, in line with the 425 sold in the US. For that size Hydor gives 4.5 W and recommends freshwater tanks of 100 to 180 liters (26 to 48 gallons) or marine tanks of 64 to 100 liters (17 to 26 gallons). Hydor rates the magnet for glass up to 10 mm (0.39 inch), thinner than the listing's half inch, so go by the maker's figure. Hydor also says the pump can be wired to a controller and switched at intervals of seconds, minutes or hours, which gives a steady pump some variation.

Aqueon's 500 GPH circulation pump is recommended for 20 to 40 gallon aquariums, with a ball-and-socket joint for aiming and an easy-lock suction cup, according to Aqueon, which backs it with a limited lifetime warranty. For freshwater tanks with dead spots, or a fish-only marine tank, it is the simplest fix.

Aqueon's page adds a draw of 3.3 W and a 4.5 by 2.375 by 3.5 inch body. Its instructions say to keep the pump fully under water whenever it runs, and to form a drip loop in the cord so water cannot travel along it into the outlet.

Jebao's SCP-90 is a crossflow pump, an 11 by 2 by 1.5 inch bar that pushes a wide sheet of water rather than a single jet, at 25 W DC, according to its listing. The listing assumes 2,700 to 3,300 gallons per hour of crossflow for the whole tank and includes a controller with wave modes. The warranty is 180 days.
