I use Seachem Clarity for cloudy water OR better still a water change with prim and stability. **Q: How often should I use this product** A: If your tank is cycling, you can use it everyday for 7 days. Adding a few fish on the 3rd day. You have to read the bottle for how much stability to use verses the size of your aquarium. If your tank is cycled and mature you can use it after you do a water change. ## Frequently Bought Together - Seachem Stability - For Freshwater and Marine Aquariums 250ml - Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 250 ml - API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored --- ## 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.us/products/48995708-seachem-stability-aquarium-stabilizer-for-freshwater-and-marine-aquariums-250ml](https://www.desertcart.us/products/48995708-seachem-stability-aquarium-stabilizer-for-freshwater-and-marine-aquariums-250ml) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
