To detoxify the ammonia produced in the reduction process. Description Prime is the complete and concentrated conditioner for both fresh and saltwater. Prime removes chlorine, chloramine and detoxifies ammonia. Prime converts ammonia into a safe, non-toxic form that is readily removed by the tank's biofilter. Prime may be used during tank cycling to alleviate ammonia/ nitrite toxicity. Prime detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them. It will also detoxify any heavy metals found in the tap water at typical concentration levels. Prime is non-acidic and will not impact pH. Prime will not overactivate skimmers. Use at start-up and whenever adding or replacing water. When transporting or quarantining fish, use Seachem StressGuard. When adding new fish, use Stability. Both are ideal for use with Prime. A single 100 mL bottle will treat 1000 US gallons of tap water. Prime will remove both chloramines from municipal water supplies. Prime also contains a binder which renders ammonia, nitrite, and non-toxic. It is very important to understand how those two functions work together. The reduction process also breaks the bonds between chlorine and nitrogen atoms in the chloramine molecule, freeing the chlorine atoms and replacing them with hydrogen to create ammonia. Prime promotes the natural production and restoration of the slime coat rather than relying on artificial or non-native slime compounds. A further bonus for the reef hobbyist , Prime will not overactivate protein skimmers.

So a 35% change on 55 gal. tank, takes 1/4 cap? Sounds too good to be true.** A: Per Seachem's instructions, if you are doing a partial water change of 35%, if you are adding water directly from the tap (such as with a water changer such as a Python or Aqueon) you add enough Prime for the volume of the whole tank. On the other hand, if you're removing 35% and then adding the water using a bucket, you can dechlorinate the amount of each bucket. For example, if you're using a 3 gallon bucket, 6 drops Prime per bucket, and then add that to the tank. The Prime works almost immediately, so just add the drops to the bucket, and then it is ready to pour into your tank. **Q: How long does it take to work when setting up a new tank? Thanks!!** A: this removes the chlorine, etc. almost immediately, I add it to the aquarium when doing water changes, ands just pour the water into the tank. remember this just removes the harmful chemicals, your tank will still have to cycle through the nitrogen cycle if you are setting up a new tank. **Q: I end up with alot of foam at the top of my aquariums when I add prime,Have I added too much to my tap water changes,My Tap water is high in iron** A: The small bottle of prime has a flip cap which allows you to add drops. If you have the large bottle of Prime use an eye dropper. When doing a water change, fill a clean, never seen soap or chemicals bucket of fresh water and add Prime to this fresh water, not directly into your tank - 2 drops per gallon. I also do not get foam. I do a 50 - 60 percent water change weekly along with a gravel vac. If you are stll getting foam after a gravel vac and water change I would suggest you give Seachem a call. They have great customer service. When cleaning your tank, give your filter sponge, floss a swish around in used tank water also to remove some of the gunk and put right back in. Do not rinse in untreated fresh water, by doing so you can lose your cycle. **Q: I'm looking to remove chlorine from my pool, will this work?** A: It will work but there may be less expensive options from a pool dealer. It decholorinates any typerson of water. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Product *by J***N on 23 January 2026* Highly recommended product ### ⭐⭐⭐⭐⭐ Must have for aquarists! *by D***N on 22 September 2024* You'll definitely need a as the tap water isn't safe for fishes, and seachem prime is one of the best out there. ### ⭐⭐⭐⭐⭐ Excellent product *by F***D on 12 November 2024* Products is very effective in reducing chlorine content and required only 5ml for 200L of water. ## Frequently Bought Together - Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 100 ml - API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored - Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1) --- ## 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.jp/products/253756833-seachem-prime-100-ml-tap-water-conditioner-for-fresh-salt](https://www.desertcart.jp/products/253756833-seachem-prime-100-ml-tap-water-conditioner-for-fresh-salt) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-20*
