It takes out all oxygen from water in a matter of seconds. After adding this to my fish tank and sticking to guidelines I almost killed all my tank with fish worth almost £1000. I had to change almost all water in my 650 litres tank and I had to do it immediately as my fish were suffocating. I'm not sure if all my fish will recover. There is no information on that canister that this affects the tank so badly. --- ## 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.ph/products/298899226-sera-nitrit-minus-250-ml](https://www.desertcart.ph/products/298899226-sera-nitrit-minus-250-ml) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-23*
