Review on 🐠 CNZ 10-Pack 1-inch Grey Mineral Bubble Release Aquarium Air Stone Airstone by Gloria Shaw

Working. However, if you want smaller and more tolerant small fish bladders or betta sorority tanks, these are not the rocks you are looking for. They eject fairly large bubbles, just from below and above. This makes them ideal for your bubble filters where you simply drop the aerostone into the tube. They are also great for fish that love fast moving water when used in conjunction with a feeder filter or canister filter. (CERTAINLY). They do much more harm than good to fish children. If using egg cups of any kind, stay away from these rocks, they will literally shake the eggs in a very short time.
