“I recently purchased a Dalua No Mess Water Changer from TechDen. The pickup tube is adjustable in length, and can be lowered to the bottom of the tank for full removal, or part way for partcial removal of water. It can be fastetened to the side of the aquarium with screws, and the priming pump is effective and efficient. It comes with a choice of covers for the inlet pipe. There cage to prevent fish from being sucked up, and a wider opening that can be used to vacuum the gravel. Very happy with it.”
