AQUANEAT Powerful Aquarium Adjustable Hydroponic Review

Ultra Silent: Dual housing structure for sound insulation; 4 rubber feet attached to the bottom to minimize vibration. Powerful: Total output 250 GPH, 10W; capable of producing sufficient air to run multiple air stones, sponge filters, bubble bars, air discs, an under gravel system or hydroponic growing system. Adjustable Air Flow: An easy-to-access control knob on the cord. Dimension: 6 x 5.5 x 4 inches (L x W x H); the quietness and the power make it a perfect choice for large tanks, multiple aquariums, and living room fish tank.(Note: This air pump is much more powerful than regular air pumps, and some ordinary check valves can't stand the air flow and make whistling sound. In this case, you can remove the check valve and place the air pump higher than the water level.). Package includes: 1 x Air Pump, 2 x 2-outlet Gang Valves (easy to individually adjust air flow to different tanks.).
