Review on 🐠 Pawfly Large Air Stone Cylinder: Enhancing Aeration in Ponds and Fish Tanks by Daniel Hhneverdie

Revainrating 1 out of 5

Very disappointed with these Air Stones

I work in a fish retail store and am always looking for products to enhance my personal and shop tanks. We have vents that work perfectly and wanted to add vents to some of the other tanks and bought them because of their size. Unfortunately, size doesn't matter if the bubbles/air just come out of the top of the stone. And big bubbles at the same time. So I "sealed" the top of the balloons with silicone caulk in hopes that air would continue to flow into the balloon. That didn't happen. Therefore, these large bubble stones are better suited for paperweights than for aquariums.

Pros
  • Medium Bubbles: Micro-hole air stones create abundant dense bubbles around the cylinders, increasing oxygen levels and promoting aquatic life in your aquarium.
Cons
  • no automatically
