Review on 🌊 VIVOSUN 5" Hydroponics Aquarium Tank Pump Air Stone Disc with Shell by Angie Creek

The only reason I give this product 3/5 is because there are areas on the back where the bubbles don't go. You see an explosion of air/bubbles escaping throughout the stone, but it's really just the surrounding edges that are allowing air to escape and creating a ring of bubbles, so it's a bit misleading. Also, this product turned out to be larger than I expected, which isn't necessarily a bad thing. On the plus side, my fish love it. My pregnant guppy (Blueberry) loves to sneak up to where the bladder gap is and cool off in the middle.
