Review on 🐠 REDGO Silent 2 Air Bubble Disk Stone Aerator for Aquarium, Fish Tank, Pond Pump, Hydroponic Oxygen with 2M Silicone Tube by Anna Jackson

The item was great but one of the rocks didn't bubble. I tried connecting it to another air pump from one of my other aquariums but it still didn't work. It's probably defective, but I don't want to return the whole item just because one stone doesn't fit. The only way to get a replacement is to return the whole item and I really don't want to take a working bubbler out of the aquarium as it needs circulation. Other than that the air pump and a stone work great, I just need to buy a new stone to connect to the air pump.
