Review on 💦 Enhance Water Circulation and Lighting with Hitauing 1600 GPH Aquarium Wavemaker Powerhead featuring LED Display Controller, Perfect for Marine and Freshwater Fish Tanks by Mary Beauchene

I was surprised that the product came in its own packaging - and it wasn't secured with tape. I put a shipping label on it and it was a door. I chose this model over others because of the 9 point speed range and the fact that it can return to its settings after a power outage. The controls are easy to use with a strong directional flow. There is one Humming noises for a while with every speed change, while the propeller and shaft settle down and the unit runs reasonably quietly, I then replaced a Hydor Koralia Nano 425, which was quiet compared to the Hitauing Edit: after about a week the humming engine knocking became more frequent in the morning Acceleration stubborn and very annoying A significant pro blem with the ability of the fork to hold the head in the position you specified. DO NOT RECOMMEND.
