Value: Because it is so concentrated (just 5 mL treats 50 gallons), you use significantly less product per water change. It saves a lot of money in the long run.Safety Net: Beyond removing basic tap water toxins like chlorine and chloramines, it detoxifies ammonia and nitrites for up to 48 hours. This is an absolute lifesaver during tank cycling or an unexpected mini-cycle crash. Fish Health: It helps stimulate your fish's natural slime coat without adding artificial slime compounds. The sulfur odor is normal and lets you know the chemical binders are active, so don't be alarmed by the smell! It is an essential item in my fish-keeping kit! Review: 20+ Years of Flawless Performance! - As someone who's been deeply involved in the aquarium hobby for over two decades, I can confidently say that Seachem Prime is, without a doubt, the single most essential product in my fish room. I was introduced to Prime when I first started out, and it quickly became the cornerstone of my water care routine. Twenty-plus years later, it remains the only water conditioner I trust and use in all my tanks. Prime does exactly what it promises, and it does it exceptionally well. It instantly neutralizes chlorine, chloramine, and ammonia, making tap water safe for your aquatic inhabitants. Beyond that, it detoxifies nitrite and nitrate, which is a huge bonus, especially during cycling or in emergency situations. The fact that it does all of this in a concentrated formula means a little goes a very long way, making the 1L bottle incredibly economical and long-lasting. What truly sets Prime apart, for me, is its reliability and the peace of mind it provides. I've never had a single issue with water parameters or fish health that could be attributed to Prime. It's truly a "set it and forget it" product that allows me to focus on the joy of the hobby rather than worrying about water quality. If you're new to the hobby, do yourself a favor and start with Prime. If you're a seasoned aquarist looking for the best, you already know what I'm talking about. I exclusively use Seachem products in my tanks because their quality and effectiveness are unmatched, and Prime is the shining star of their lineup. This isn't just a water conditioner; it's an investment in the health and longevity of your aquatic ecosystem. Five stars, hands down! ## Features - Concentrated conditioner for marine and freshwater aquarium use - Removes chlorine & chloramine and also detoxifies heavy metals - Makes ammonia, nitrite, & nitrate safe yet available for nitrifying bacteria ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007R5LW5S | | Best Sellers Rank | #499 in Pet Supplies ( See Top 100 in Pet Supplies ) #1 in Aquarium Water Treatments | | Brand | Seachem | | Brand Name | Seachem | | Customer Reviews | 4.8 out of 5 stars 43,645 Reviews | | Included Components | Seachem Prime Water Conditioner, 2 Liter | | Item Form | Liquid | | Item Type Name | Seachem Prime Water Conditioner, 2 Liter | | Item Weight | 2.18 kg | | Liquid Volume | 2 liters | | Manufacturer | Seachem | | Manufacturer Part Number | MACC24-500 | | Model Number | MA24WW500 | | Number of Items | 1 | | Pet Type | Fish | | Target Species | Fish | | UPC | 000116043809 | | Unit Count | 1 Count | | Warranty Description | Warranty | ## Product Details - **Brand:** Seachem - **Item Form:** Liquid - **Liquid Volume:** 2 liters - **Manufacturer:** Seachem - **Unit Count:** 1 Count ## Images ![Prime Water Conditioner, 2 Liter - Image 1](https://m.media-amazon.com/images/I/71Jd-atspBL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Does this lower pH balance?** A: No, it does not affect PH. **Q: does this product have an expiration date?** A: There’s no expiration date on the bottles **Q: Can I use it for outdoor ponds?** A: I've been using it in my ponds for about 6 months and I haven't had any problems.

Five stars, hands down! ### ⭐⭐⭐⭐⭐ Great product *by J***S on April 6, 2025* From Cichlids to Fancy Goldfish I've been keeping fish for 30+ years.Just about every major manufacture and boutique specialty company has a water conditioning and treatment product.I can't say I've tried them all, but close too it. Some products have at the least, minimal effectiveness while others can be potentially dangerous. An example would be Stress Coat which has binding sugar strands in the Aloe. This isn't a problem unless one of your fish has a small scratch or wound.The sugar feeds the bacteria which can lead to major infection and dire consequences.I've been using Amquel for years and it's a fine conditioner, excellent at removing chlorine, and Chloramines, but like all these products - they come with limitations. Well, with one exception and that's Prime by Seachem. A few months ago, I decided to give it a try, and haven't looked back since. Prime doesn't just remove the chlorine and Chloramine it does much more: * Detoxifies any and all heavy metals in your tap water (you can call your water company directly for a list of them and PPM) * Neutralizes Ammonia * Neutralizes Nitrite * Neutralizes high Nitrate to non toxic levels * Removes toxic gases * Will not foam or change PH * Helps regenerate natural slime coat Since using Prime, I've seen a dramatic improvement in all of my fish. In 2010 one of tanks was hit with the dreaded and rare Toxic Tank Syndrome - within 48 hours I had lost nine gorgeous fish - except for one survivor, a single Broad Tail Nymph.Since that ordeal, "Roxy" became a bottom dweller spending most of her time laying in a corner. Treatments were conservative, but nothing worked. After my first 50% water change using Prime her behavior began to improve. Now she swims among her tank mates, her color is better, gill movement stabilized and her appetite ferocious. In fact I see improvements in all my fish and in every tank.There simply isn't anything like it, Prime is hands down one of the best things you can do for your fish. In addition to the outstanding, patented formula of Prime - it couldn't be more economical to use. A single 500 ml bottle treats up to a whopping 5,000 gallons of water. A tiny bit goes a long, long way.It should also be noted that in times of emergency the dose can be increased five times, Prime is harmless to fish.It's the only product of it's kind, and towers above any other water treatment on the market - period. If your an aquarium hobbyist be it novice or advanced - I would urge you to add a bottle of Prime to your arsenal of fish care products. Your finned friends will thank you for it. ## Frequently Bought Together - Seachem Prime Water Conditioner, 2 Liter - Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums 2L / 67.6 oz - Seachem StressGuard Slime Coat Protection - Stress and Toxic Ammonia Reducer 500 ml --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/221317122-prime-water-conditioner-2-liter](https://www.desertcart.at/products/221317122-prime-water-conditioner-2-liter) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-10-15*
