Many hobbyists have both which allots them to swap out their 200 micron socks from time to time. **Q: How often should I changes the filter socks?** A: It depends on tank load, but generally you want to change your filter socks once a week or every two weeks. The more often you change, the better your water quality; it removes organic solids before they break down in aquarium. **Q: Is it better to use a longer sock or a shorter sock?** A: Ideally the filter sock should be hanging in the water without touching or laying on the bottom of the sump. If a shorter sock is above the water line, there may be more noise as water drains from the sock side and splashes. **Q: What is the glaze finish on the sock?** A: The socks are untreated and are designed with a 100% aquatic safe outside glaze. We do recommend giving them a quick rinse to prevent foam build up. **Q: Will these socks work with a reefer?** A: No, We have personally tested our filter socks in the reefer sliding shelf sock holder. Our material is thick and our plastic ring is slightly too large to drop through the hole in the shelf. ## Frequently Bought Together - Aquatic Experts 4 inch Ring Filter Socks 200 Micron, Filter Socks for Saltwater Aquarium, Sump Filter Sock, Felt Aquarium Socks, Reef Filter Sock (2 Pack, 4" x 14") - Bubblefin Pre Sump Filter Sock Holder 4" with 2 x Filter Bags - Reefing Art Ceramic Bio Filter Media Vast Surface Area for Aquarium Sump Canister (1 Box / 24 pcs) --- ## 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.ro/products/9746879-felt-filter-socks-4-inch-ring-style-200-micron-aquarium](https://www.desertcart.ro/products/9746879-felt-filter-socks-4-inch-ring-style-200-micron-aquarium) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-31*
