Review on The Ultimate Solution for Maintaining a Clean and Safe Aquarium: BPA Free TERAPUMP TM TRDP40 Original Aquarium Cleaner Siphon Pump by Dana Martin

Made cleaning my 3.5 gallon tank so much faster and easier. All you have to do is put the suction side in the aquarium and attach the suction cup to the disc. Place the other end in the bucket. Squeeze the blue bulb about 4 times and the water will start flowing from the reservoir into the bucket. There is a lid with small holes to keep your fish and gravel from being sucked in; however, it absorbs everything else that pollutes the water. When you're done, quickly rinse and put away. It's comfortably small, so I keep it right in the bucket. I definitely recommend it.
