Good size. *by K***R on 12 April 2025* Good socks. Like the top rim. Fast shipping. ### ⭐⭐⭐⭐⭐ Aquarium sock filters *by F***N on 27 January 2026* Fit perfect and filter great ### ⭐⭐⭐ Clogs quickly (using sanded as substrate) *by D***S on 30 November 2025* Great price and very well made but both socks become clogged in one day. In their defense I have a sand bed and messy stingrays but BRS 200micron socks last 3-4days before clogging If you change the socks in your system daily these would be great! ## Frequently Bought Together - Blue Donuts Filter Sock 200 Micron, 4 Inch Ring by 8 Inch Long, Aquarium Filter Sock, Saltwater Filter Socks, Pack of 8, White - Polyplab - Reef-Roids- Coral Food For Faster Growing - 75g --- ## 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.es/products/603593912-blue-donuts-filter-sock-200-micron-4-inch-ring-by](https://www.desertcart.es/products/603593912-blue-donuts-filter-sock-200-micron-4-inch-ring-by) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-25*
