When the filter is plugged in you have to pour water in the sponge section until the flow is started, which is an inconvenience as I stop the filter everytime I give food to my fish. So keep in mind if you are buying this filter as you have to keep pouring water everytime you restart. ### ⭐⭐⭐⭐ Aquarium Water Filter 🐟 🐟 🐟 *by on Reviewed in the United Arab Emirates 29 May 2026* Good use, no problems. without a quiet sound --- ## 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.hr/products/577479275-mumoo-bear-fish-tank-water-filter-plastic-transparent-waterfall-hang](https://www.desertcart.hr/products/577479275-mumoo-bear-fish-tank-water-filter-plastic-transparent-waterfall-hang) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-24*
