Box Contains water treatment Review: Prime is the best product and at a great price - Great for fish keeping, halves the use of other brands and keeps the water perfect, I only use this one now and it's a great price too Review: Have been using this for years - I've been using Seachem Prime Water Conditioner for years. One of the things I appreciate most about Seachem Prime is that it's very concentrated. I only need to use a small amount of the conditioner to treat my entire tank, which means that a single bottle lasts for a long time. This is particularly important for me, as I have a large tank and was previously using a less concentrated water conditioner that required me to use more of the product. Another great thing about Seachem Prime is that it's very easy to use. I simply add the recommended amount of conditioner to my tank each time I do a water change, and it does the rest of the work. Seachem Prime also has the added benefit of not affecting the pH level of my tank. This is particularly important for me, as I have a delicate ecosystem in my tank that requires a consistent pH level. I've found that some other water conditioners can cause fluctuations in pH levels, which can be harmful to my fish and plants. With Seachem Prime, I don't have to worry about this issue. Overall, I would definitely recommend Seachem Prime Water Conditioner to any fish owner looking for an effective and concentrated water conditioner. It does a great job of detoxifying tap water and keeping my fish healthy, without affecting the pH level of my tank. Plus, the concentrated formula means that a single bottle will last for a long time, making it a great value for the price. ## Features - Warning:Not suitable for children under 10 months. - Complete and concentrated conditioner for both fresh and saltwater - Removes chlorine, chloramine - Detoxifies ammonia, nitrite, and nitrate - Model number: 020042 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002568S6 | | Allergen Information | Gluten Free | | Best Sellers Rank | 313 in Automotive ( See Top 100 in Automotive ) 7 in Greases & Lubricants | | Brand | Seachem | | Brand Name | Seachem | | Country Of Origin | USA | | Customer Reviews | 4.8 out of 5 stars 37,736 Reviews | | Global Trade Identification Number | 00000116043601 | | Included Components | Water conditioner | | Item Form | Liquid | | Item Type Name | Seachem Prime Water Conditioner | | Item Weight | 10.2 Ounces | | Item form | Liquid | | Item weight | 10.2 Ounces | | Liquid Volume | 250 Millilitres | | Liquid volume | 250 Millilitres | | Manufacturer | Seachem | | Manufacturer Part Number | 075223 | | Model Number | 67104360 | | Number of Items | 1 | | Number of Packs | 1 | | Pet Type | Fish | | Product Warranty | 2 years | | Target Species | Fish | | UPC | 634252024745 000116043601 707005178771 | | Unit Count | 250.0 millilitre | | Unit count | 250.0 millilitre | ## Product Details - **Brand:** Seachem - **Item form:** Liquid - **Item weight:** 10.2 Ounces - **Liquid volume:** 250 Millilitres - **Number of Packs:** 1 ## Images ![Seachem Prime Water Conditioner, 250 ml - Image 1](https://m.media-amazon.com/images/I/61aPb4rk8cL.jpg) ![Seachem Prime Water Conditioner, 250 ml - Image 2](https://m.media-amazon.com/images/I/81Q5CnYWOkL.jpg) ![Seachem Prime Water Conditioner, 250 ml - Image 3](https://m.media-amazon.com/images/I/61DVJNjihJL.jpg) ![Seachem Prime Water Conditioner, 250 ml - Image 4](https://m.media-amazon.com/images/I/61QTPBg3NNL.jpg) ![Seachem Prime Water Conditioner, 250 ml - Image 5](https://m.media-amazon.com/images/I/71b79qr2yXL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Instruction reads use 1 capful for every 50 gallons of new water. 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 ### ⭐⭐⭐⭐⭐ Prime is the best product and at a great price *by M***H on 27 September 2026* Great for fish keeping, halves the use of other brands and keeps the water perfect, I only use this one now and it's a great price too ### ⭐⭐⭐⭐⭐ Have been using this for years *by P***M on 1 April 2023* I've been using Seachem Prime Water Conditioner for years.
