I have a 10gal tank with a 10-20gal filter.** A: It's designed to fit exactly in a Fluval C4....not sure it will fit your need.. **Q: Can I use c2 nodes in a c4 filter** A: Sorry, I haven't a c4filter, I have only a c2 and a c3 filter. But it's very useful for them. **Q: How often do you change ammonia remover bag?** A: About every 4 weeks. **Q: how often do you change the carbon filters** A: I change them every 2-3 weeks, but I have very large African Cichlids and they can be messy. After they absorb to their capacity they are no good anyway, so you need to change them, but they do a very nice job keeping the water clear. You should also check out the C4 Zeo-Carb 3-pack. I switched to those and they offer the carbon plus ammonia absorbtion which has worked great for my tanks. They are a little bit more expensive than the plain C4 Carbon 3-pack, but still cheap overall. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install *by M***R on January 9, 2026* Works well ### ⭐⭐⭐⭐⭐ Flu all filters *by E***Z on September 19, 2025* Great product fixed my filter system perfectly ### ⭐⭐⭐⭐⭐ Fits perfectly. *by A***S on October 2, 2025* Perfect replacement. ## Frequently Bought Together - Fluval C4 Carbon - 3-Pack - Fluval C4 Poly Foam Pad - 3-Pack - Fluval C4 Bio-Screen - 3-Pack --- ## 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.co.uk/products/6811985-fluval-c4-carbon-3-pack](https://www.desertcart.co.uk/products/6811985-fluval-c4-carbon-3-pack) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
