You need a strong pump to get the job done right.I was a little disappointed as the photo make it looks like it produces a lot more bubbles (as did some of the other reviews), but it does get the job done. I have a 10 gallon tank and ordered the 4.25 inch bubbler. I do have rocks over it so my bubbles are a bit bigger than the tiny ones (which is part of why it doesn't seem to produce as many) but even before I added the rocks it didn't produce as many bubbles as depicted/hoped for (yes, I did follow directions and soak first). All in all, it works and the fish enjoy swimming through the bubbles so I consider it worth the purchase. ### ⭐⭐⭐⭐⭐ Steady stream of bubbles! *by F***Z on March 21, 2018* I've had the stone for about one week now, and what I can say is that it's well made. It is very solid and seems to be assembled well. The included suction cups do their job and hold it in place really well.The only downside I see so far, is that there aren't bubble coming from the whole stone, but rather around it's edge. This still makes for more than enough bubble, I even used the valve on my air pump to turn it down a bit.I would highly recommend this stone for anyone looking to get more air in their tank and have a nice dense stream of bubbles to add to the aesthetic of the aquarium. ### ⭐⭐⭐⭐ Worth the money *by D***. on June 8, 2024* The media could not be loaded. I think it does a great job. Blends in well with rocks. The only problem I had was attaching the bubbler to air hose. I had to widen air hose to get it fit. ## Frequently Bought Together - AquaticHI Large Round Disc Air Stone/Diffuser for Oxygenation in Fresh/Saltwater Tanks, Ponds, Hydroponic, Aquaponics, and as a Decorative Airstone for Aquariums (4.25 inch) - PENN-PLAX Standard Airline Tubing for Aquariums – Clear and Flexible – Resists Kinking – Safe for Freshwater and Saltwater Fish Tanks – 8 Feet - boxtech Upgrade Aquarium Air Pump, Ultra-Quiet Fish Tank Oxygen Pump with Adjustable Airflow, Powerful Air Pump with 2 Outlets to Pump Rich and Fine Air Bubbles --- ## 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.co.uk/products/47823105-large-round-disc-air-stone-diffuser-for-oxygenation-in-fresh](https://www.desertcart.co.uk/products/47823105-large-round-disc-air-stone-diffuser-for-oxygenation-in-fresh) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
