Review on Tetra Whisper Easy Aquariums Non UL Fish & Aquatic Pets by Kristi Martinez

I have several aquariums. I use this air pump for my sponge filters. I tried one of the newer air pumps, too useless, the tetra pump is an old, simple, easy to use and very reliable air pump. I have 6 or so. One has failed after a little over 3 years of continuous use and I have another that has been running very quietly for over 8 years until it hits something really reliable. I would highly recommend this pump
