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! Review: Väldigt drygt och räcker länge. - Grymt bra och väldigt drygt. ## Features - POWERFUL TREATMENT: Seachem Prime is a complete and concentrated conditioner for both freshwater and saltwater fish tanks, working hard to remove chlorine and chloramine. - REMOVER: Seachem Prime immediately and permanently removes chlorine and chloramine, successfully allowing the bio filter to remove ammonia, nitrite, and nitrate while they are detoxified for 48 hours. - DETOXIFIER: Seachem Prime effectively detoxifies ammonia, nitrite, and heavy metals found in the tap water at typical concentration levels, providing a safe environment for your betta, tetra, or other fish. - USE: Use 1 capful (5 mL) of Seachem Prime for each 200 L (50 US gallons) of new or replacement water. For best results, add Seachem Prime to new water first. For exceptionally high chloramine concentrations, a double dose may be used safely. For smaller volumes, use 2 drops per gallon. - SAFETY: In case of an emergency, the 5x dose of Seachem Prime may be used for both ammonia and nitrite. Use a ½ dose if the water temperature is > 30°C (86°F) and chlorine or ammonia levels are low. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MRSR0K1 | | Allergen Information | Sulphur dioxide may contain | | Best Sellers Rank | #64,369 in Pet Supplies ( See Top 100 in Pet Supplies ) #1,323 in Water Treatments | | Brand | Seachem | | Brand Name | Seachem | | Customer Reviews | 4.8 out of 5 stars 1,784 Reviews | | Global Trade Identification Number | 00000116043700 | | Included Components | water conditioner | | Item Form | Liquid | | Item Weight | 33.8 Ounces | | Liquid Volume | 1 Litres | | Manufacturer | Seachem labs | | Manufacturer Part Number | FBA_437 | | Model Number | 437 | | Net Quantity | 1000.0 Milliliters | | Pet Type | Fish | | Target Species | Fish | | UPC | 000116043700 | | Unit Count | 1000.0 Milliliters | ## Product Details - **Brand:** Seachem - **Item Form:** Liquid - **Item Weight:** 33.8 Ounces - **Liquid Volume:** 1 Litres - **Manufacturer:** Seachem labs ## Images ![Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 1Litre - Image 1](https://m.media-amazon.com/images/I/61ECqGGw6iL.jpg) ![Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 1Litre - Image 2](https://m.media-amazon.com/images/I/712BR2Ug8cL.jpg) ![Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 1Litre - Image 3](https://m.media-amazon.com/images/I/819paBHS6RL.jpg) ![Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 1Litre - Image 4](https://m.media-amazon.com/images/I/91ElptHhL2L.jpg) ![Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 1Litre - Image 5](https://m.media-amazon.com/images/I/81KUw5NtI+L.jpg) ## Questions & Answers **Q: Have a180 gallon tank and i do 25% water change every week? how many amounts i should put??? do i also put before putting water or after putting water** A: I did a 50% change every week because goldfish are pretty dirty. Just add it when you put the new water in the tank. The dosing directions are on the bottle. My well water is high in nitrate and Prime helps to keep it under control. **Q: So if I have a 3g bucket, how many ml would I dose with?** A: Each thread represents 10 g. I had a 10 g tank and used 2 caps to get the levels to 0(zero) **Q: Does prime detoxify nitrates for invertebrates?** A: yes its safe for all **Q: Api stress coat or prime, which is better and why?** A: The 2 products are nothing of the same. API stress coat is for coating your fish with a stress relieving cost and it can make tap water safe. Prime is for making tap water safe and detoxing any ammonia, nitrates and nitrites. Prime will actually reduce harsh components found in your water. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 20+ Years of Flawless Performance! *by A***A on 29 May 2025* 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.
