Review on 🌬️ SunGrow Air Stone Bars: Powerful Aeration and Water Movement (4-Pack, 4 x 0.8 x 0.5 Inches) for Optimal Oxygenation and Bubble Creation by Amber Marie

I hate writing bad reviews but in this case I don't want others to buy this product. These air vents may look just like the ones you have bought in the past, but unfortunately they are complete fakes. When I tried to attach the air hose to the stone; The plastic part on the stone is being pulled out of the stone. Which could not be returned to its place to do its job of connecting the air line to the stone. And 2 out of 4 that actually worked; unfortunately not for long. I was trying to just move the rocks to other parts of the tank when I did that one came loose and the other couldn't be attached to another line because it broke when I tried to get off the previous line to solve. Well it's a joke! I mean, I know I used to be able to put these types of stones on different lines with no problem. So it's because of the cheap sticky adhesive materials that don't allow this brick to be used on its air hose the way it should.
