The only issue is one of the stones needed to the stem to be hot-glued to the center. Once I did that I had 2 beautifully working aeration stones at a good price! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Love these more than the other types on amzon *by B***R on Reviewed in the United States πŸ‡ΊπŸ‡Έ on February 23, 2021* Love these stones wish I would of went with these instead of the big 4” round ones only because after I got those the add was miss leading so I had to buy more stones and went with these. For my 20w pump these would of been better flow I have to limit these down a little so the 4” round ones will let air thru them . ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars In a comparison test, this seems to work great for DWC *by G***3 on Reviewed in the United States πŸ‡ΊπŸ‡Έ on August 4, 2020* I have tested this 4 inch cylindrical stone with two other styles. The other two styles stopped working effectively after less than one week. I have 8 of these stones running off of one 1110GPH pump and they still produce an ample supply of air with no noticeable decline in efficiency after three weeks. I am purchasing more to have on hand. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/70456214-aquatichi-2-pack-large-4-inch-100-mm-cylinder-air](https://www.desertcart.tn/products/70456214-aquatichi-2-pack-large-4-inch-100-mm-cylinder-air) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-21*
