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

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…
