## Description

Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 50 ml

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: Worked great to prep our tank before adding fish, just very concentrated so measuring matters - We used this conditioner when setting up our tank and it made the whole process much less stressful. It was reassuring knowing the water was treated properly before introducing any fish, and the tank looked clear and stable very quickly. After using it, everything tested where it should be, and when we finally added our fish they adjusted without any issues, which told us it was doing its job. I really like that a little goes a long way, so the bottle should last quite a while even with regular water changes. It gave us peace of mind during setup and made us feel confident that we weren’t putting our fish into unsafe water. The only downside is that the dosing is very concentrated, so you have to measure carefully especially with smaller tanks to avoid adding too much. Overall, this is a solid conditioner that worked exactly as advertised and helped get our tank ready the right way before adding fish.

## 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 ideal 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.

## 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.

### ⭐⭐⭐⭐⭐ 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.
