Air Stones Long-Lasting Bubble Bar Aquarium Fish Tank Aerator Pump Hydroponics 8"

I received a 12" stone when it clearly states in the product description that it's an 8" stone, which I ordered. Too large for my application. It also came BROKEN IN 3 PIECES, which ALMOST ended up being a blessing in disguise because what was left attached to the air nipple was exactly 8" of the stone. I say ALMOST because after I plugged it into my pump it only blows bubbles from the first 3/4" of the stone. At least is wasn't too expensive, not going to even bother with trying to contact seller to replace.
