It is heavy enough to sink to the bottom and stay in position while stirring the tea. The squared ends protect it from the fine sediment that clogs other airator stones. It emits very fine bubbles and I think it's heavy duty enough that it will last for a long time. I have finally found a replacement for all the airators that clogged, ones that kept surfacing or were too light and others that became waterlogged and broke. I am very pleased. ### ⭐⭐⭐⭐⭐ Work well *by D***L on October 30, 2018* These work well so far with my eheim 200 air pump Have one connected to each port. A larger air pump would be better but it works for my 75 gallon tank. Produce air around most of the stones. Heavy enough to stay on the bottom. Nipple will fit two different sizes of tubing.Update: Purchased eheim air pump 400 air pump. Works very well with two of these stones. Produces LOTS of fine bubbles around complete stone. ### ⭐⭐ Leaks around the square plastic. I took the top ... *by B***L on October 29, 2016* Leaks around the square plastic. I took the top off and used silicone to seal it. When it dried and i tried using it again, the bottom leaked. Bubble are huge and very few actually come out of the stone. The silicone worked until the pressure opened up the seal on the plastic again. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/21340155-uxcell-black-mineral-bubble-air-stone-diffuser-for-aquarium-fish](https://www.desertcart.ie/products/21340155-uxcell-black-mineral-bubble-air-stone-diffuser-for-aquarium-fish) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-05*
