Had two small ones in a 56 corner tank. Removed one as it actually had too many micro bubbles!! Make sure you have a new/powerful pump (fluval Q2) ### ⭐⭐⭐⭐ Works as advertised *by K***S on May 22, 2023* I’d buy again if I needed it. --- ## 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.us/products/731873746-air-stone-disc-aquarium-fish-tank-bubbler-with-control-valve](https://www.desertcart.us/products/731873746-air-stone-disc-aquarium-fish-tank-bubbler-with-control-valve) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
