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

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!

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.

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.

Le produit a un réel impact sur les analyses d'eau, très efficace à petite dose. Seul aspect dérangeant: son odeur de soufre à l'ouverture de la bouteille. Mais une fois dans l'eau ça ne sent rien. J'ai reçu par contre une bouteille abimée, l'embouchure était tordue et une fois enlevé l'opercule, l'étanchéité était compromise, j'ai dû transvaser le produit dans une autre bouteille.

The prime cleans up the slime! It is so divine, you'll certainly not mind the word on the vine is this stuff is sublime! Make sure to choose prime, for your brine!

Great product and such a small amount required at water change. Highly recommended. I used for my newly hatched Axolotl and also my tropical fish tank.

Produit toujours au top pour mon aquarium, jamais eu de soucis et flacon qui dure souvent plus que les autres car moins dilué avec de l'eau que certaines autres marques.

Producto necesario e indispensable para todos los que tenemos acuario en casa. Rinde muchísimo ya que una sola gota trata varios litros y el efecto es inmediato. Si utilizas agua del grifo para cambios de agua es necesario utilizar prime para eliminar cloro y cloraminas. Además sirve para una emergencia temporal donde tengas un pico de amonio o nitritos reduciéndolos de manera inmediata. Es un seguro para tu acuario tenerlo en casa. Totalmente necesario y de la marca reconocida Seachem.
