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!

I find this is the best conditioner to use in my aquariums I have always used it for the past 3 and a half years and since I started to buying it on Amazon has been great as I would have to travel at least 50 miles to buy it in a pet store or aquarium shop as the nearest pet stores don't sell seacham products so buying it on Amazon is a lot quicker and more value for money
