I suggest when cycling what i found out to remove pre filters so that the bio filters and media get full colonized properly. do no use anything else and let nature take it's course. ## Frequently Bought Together - Fluval Cycle Biological Enhancer, Aquarium Water Treatment, 16.9 Oz., A8351 - Fluval Waste Control Biological Cleaner, Aquarium Water Treatment, 8.4 Oz., A8355 - Fluval AquaPlus Water Conditioner, Aquarium Water Treatment, 16.9 Oz., A8344 --- ## 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.il/products/342588559-fluval-cycle-water-treatment-500-ml](https://www.desertcart.co.il/products/342588559-fluval-cycle-water-treatment-500-ml) --- *Product available on Desertcart Israel* *Store origin: IL* *Last updated: 2026-07-07*
