Review on 🐠 Stay Cool with Marina Cool Air Pump: Efficient Aeration for Your Aquarium by Rhonda Quire

This pump is small, unobtrusive, quiet and gets the job done. Plus, the price can't be beat. I don't feel entitled to ask for more. I connected this little air pump to a ViaAqua6 LED bubbler in my 5 gallon tank and it worked great for 6 months despite being on for days. However, recently the pump started to rattle and shake. The gasket didn't help. I was afraid I would have to buy a new one. (But even if it did, it would be worth it!) Suspecting that the case had come loose, I tightened the rubber strap and am happy to report that it has returned to its still state.
