Produces a lot of bubbles with the right pump. *by on Reviewed in the United States July 23, 2026* 2”, 4” and 5” legit really good aerator stones. Produces tons of bubbles with a 12 volt pump.The 8” was a dud, a pos. Maybe I got a bad one? Large bubbles escaped on one side only. ### ⭐⭐⭐⭐⭐ Works for my live well *by on Reviewed in the United States August 3, 2026* I use this to keep my eels alive in between fishing trips. It works better than a small round stone. They swim through it and seems like they are happy. ### ⭐⭐⭐⭐ Should work for a more powerful airpump *by on Reviewed in the United States August 1, 2024* I saw some reviews saying half the stone didn't work, but I hoped for the best and purchased this product anyways. Lo and behold, when I plugged my new air stone into my 4 watt air pump, only half the stone bubbled, but the bubbles were great bubbles. Credit where credit is due. Now looking into the matter, the instruction manual claims that if only half the air stone works, then the problem is with the air pump not being strong enough. I guess my aforementioned air pump with a power of 4 watts was simply not enough. The details of this product recommend use with an air pump of > 4 watts. > is not >= I guess, and I can't say I didn't see this happening because I was warned. So yeah, unless your air pump power is greater than 4 watts, the air stone won't bubble completely, and it's a lowkey weird look. The suction cups are great though, and really hold the stone in place. --- ## 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/74878334-pawfly-aquarium-8-inch-large-air-stone-disc-bubble-diffuser](https://www.desertcart.co.uk/products/74878334-pawfly-aquarium-8-inch-large-air-stone-disc-bubble-diffuser) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-25*
