Not only is filtration essential in the aquarium, but so is water circulation. This raises the important oxygen levels which is beneficial to fish, especially in crowded tanks. Their use also helps in the reduction of algae (nutrients have less places to settle) reducing the number of dead/stagnant spots. Maintenance is therefore reduced. Having strong currents is vital to help keep corals healthy and clean. This also creates interesting activity with how the fish and other creatures move around. For freshwater aquariums too, having the extra flow is also useful. They are great for fish which come from fast flowing rivers, in Malawi cichlid aquaria and in some planted tanks. Key features • Customizable flow with 4 Modes. • Smart LED Controller. • Feeding mode. • Quiet operation. • Magnetic mounting. • Easy to maintain. Customizable flow with 4 Modes The intelligent HG951 aquarium wave maker can set various flow modes, power, and frequency according to sunrise, sunset, day, and night to simulate waves in 4 modes: • Pulse wave: simulates natural waves making the fish, invertebrates, and coral feel like they are in the sea. • Sine wave: wave flow is gentle and slow. • Constant speed wave: blows away fish wastes, uneaten food, and detritus to keep the tank clean. • Random wave: randomly uses a mix of the other 3 wave modes. Smart LED Controller The digital LED controller gives you complete control over the pump’s performance with adjustable wave speed, power levels, and timing settings. It offers four wave modes (pulse, sine, constant, and random), eight speed levels, and four working power levels (40%, 60%, 80%, and 100%). The controller divides a day into 5-time intervals, and each has a different preset wave. If you don’t like the preset waves, you can set them yourself. • Dawn (05:30–07:30): 80% power with a gentle pulse wave at medium speed. • Sunrise (07:30–09:30): 100% power with a steady pulse wave at a slightly higher speed. • Daytime (09:30–14:00): 100% power with a continuous pulse wave for maximum water movement. • Sunset (14:00–16:30): 100% power with a soft sine wave that gradually slows down. • Night (16:30–05:30): 40% power using a constant speed wave for quiet nighttime circulation. Feeding mode • The system also includes a feeding mode that pauses operation for 10 minutes, plus a memory function that automatically restores your last settings after a power interruption. Quiet operation • The safe 24-volt DC-controlled wave generator has energy-saving magnetic thrusters and motors to quietly circulate water, making soft waves, and the waves are 360-degree diffusion, eliminating dead spots. When it’s working, the sound is lower than 30dB. Magnetic mounting • You can install it anywhere using a dual-magnet system that makes installation fast and secure, even through thick glass. The pump rotates 360° for total control of water direction and flow pattern. Easy and safe to maintain • Easy to take apart, clean, and reassemble by hand. • Impeller is protected by a cage to prevent fish or other particles from entering.
