This was done after water change and within few hours instead of the water settling the same turned out to be yellowish light brown in colour.

Prime dosage is 1mL per 10g. You're wanting a total of 500mL to treat 5000g. For Safe, 1/4 of a teaspoon treats 300g. And, just to note, there are 3 teaspoons in a tablespoon. 5000/300=16.667 ||| .25tsp X 16.667 = 4.167 ||| 4.167/3=1.389So, 4.167 teaspoons in the 500mL bottle. Or for simplicity, 1.389 tablespoons. You could probably do 1 tablespoon and another 1/3 tablespoon aka a teaspoon.I've never made Safe so concentrated, you may need to use slightly warmed water to make sure everything gets saturated. Also always shake before you use it. **Q: if 5gr of safe treats 100gal then 250gr treats 5000gal, and 5ml of prime treats 50gal then 500ml treat 5000gal as well and its the same price** A: 1 gram of Safe treats of 200 gallons, 1 ml of Prime 10 gallons. 250 grams of Safe treats of 50,000 gallons, 500 ml of Prime 5,000 gallons. Thus, you get more for your money :). **Q: What is the difference between safe & prime? i currently use prime but am interested in safe for my larger aquarium i just set up** A: Safe is basically the powdered form of prime, that's what we use in our shop ( we have over 600 aquariums) **Q: Can i recharge purigen with safe?** A: Yes Please read: http://www.seachem.com/support/forums/forum/general-discussion/1771-is-safe-safe-for-purigen-re-charge strait from the Seachem support ## Customer Reviews ### ⭐ Water Turned into yellow-light brown *by J***I on 21 September 2020* As per the guidelines on the product packaging added less than 1/4th tea spoon to my 140 ltr fresh water aquarium tank so as to reduce the nitrate/nitrite and to balance the ammonia.

Just a pinch for 200 litres.. maybe even less. Seachem is expensive but it gets rid of heavy metals also this one doesn't. Overall best VFM dechlorinator in the market one can say. ## Frequently Bought Together - Safe, 250 g / 8.8 oz - Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1) - Seachem StressGuard Slime Coat Protection - Stress and Toxic Ammonia Reducer 500 ml --- ## 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.at/products/266775677-seachem-safe-250gm](https://www.desertcart.at/products/266775677-seachem-safe-250gm) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-18*
