Review on 🐠 Aneco 4-Pack Cylinder Shape Aerator Bubble Diffuser Airstones for Aquarium and Hydroponics Air Pump (4 x 2 Inch) by Stacy Lewis

I use them in mine 2 gallon bucket in your hydroponic garden. They work very well with both my 475 GPH 4-way air pump and my 110 GPH 2-way air pump. I also have one that runs in a 16 gallon tub that has my 3 tomato plants in right now and they are growing like CRAZY! Excellent quality and price. One thing to note, I have ordered them from another company in the past and the other company put caps on the ends of the stones which helped prevent the box they came in from being punctured became. They weren't protected, but that didn't affect the quality. quality anyway. Just thought I'd include that in case anyone needs to know. They also seem to apply more sealant around the connector than other brands. So far, so good. They work great! 5 Stars!
