You can replace one cartridge at a time to keep your nitrogen cycle even. I need to replace one cartridge about every 3-4 weeks.

You can replace one cartridge at a time to keep your nitrogen cycle even. I need to replace one cartridge about every 3-4 weeks. Be sure to rinse the filter first—otherwise you’ll get activated carbon black runoff into the water. ### ⭐⭐⭐⭐⭐ Price and workmanship *by B***H on December 5, 2025* Great filter. Water stays clear for 2 weeks, ### ⭐⭐⭐⭐⭐ Awesome filters *by E***3 on February 9, 2026* These have helped me so much. I have an African clawed frog. She is picky about filtration. And makes a ton of waste. This filter is quiet and allows for a lower water level. I like that it’s skinny too. I really love these refills they are easy to use as well. Just slam them in and you’re good to go! --- ## 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.pl/products/84733775-marina-slim-filter-carbon-plus-ceramic-cartridge-18-count](https://www.desertcart.pl/products/84733775-marina-slim-filter-carbon-plus-ceramic-cartridge-18-count) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
