Seachem Laboratories Prime is a highly concentrated 250 ml water conditioner designed for both fresh and saltwater aquariums. It instantly neutralizes harmful chlorine, chloramine, and ammonia, detoxifies nitrite and nitrate to support biofilter efficiency, and removes heavy metals at typical tap water levels. Prime also promotes the natural slime coat regeneration in fish, is pH neutral, and won’t overactivate skimmers, making it an essential solution for tank cycling, water changes, and maintaining a healthy aquatic environment.

Great Product!!
The story starts with my old established tank being broken by relatives kid and it just broke glass on base and one side. i have large angels, peacock rainbows, corycats and bosemani ranibows. i decided to make a new tank instead of fixing the old one, due to the size issues i had to give it 3 days after siliconing it to let it dry out, by that time the bacteria in my filter might not have survived as there was no circulation in filter. i brought prime to cure my issue of new tank syndrome as it was going to be a fully stocked tank, thankfully i had my sponge filter working in bucket so it had the bacteria colony from my old tank. seachem prime did what it was suppose to do, it helped me set up a tank and i just lost 1 fish. Its costly but considering its a highly concentrated solution and you just need 7ml for 300L (my tank is actually 290L) it would last you a long time. if you use any chlorine remover, you can replace it with this. it also converts ammonia/nitrate. please do remember adding this is not the end all of your regular maintenance, you will still need to change the water depending on stocking level of your tank and tank size. i highly recommend this and in long run it turns out to be around same cost as any other item.

Value for Money
Highly concentrated require very less quantity to de-chlorinate my entire 150 gallon tank just 3 full caps....can use prime before directly in tank along with fish and use chlorine water directly into the tank during water change... dechlorinate water instantly

Life saver! Literally.
This is the gold standard of water conditioners. Its ammonia and nitrite removal in a bottle. Test water params with reagent based kit, like API, and use this if ammonia or nitrites are too high. Also use to dechlorinate the water.

Good to start cycling a tank
Good bacteria build up is seen and nice rise in levels of nitrates. Still in process of cycling can update the result later

Must for aquariums.
Good one, chlorine dissipates easily even without using any conditioner, but this Prime removes chloramine as well along with other heavy metals n ammonia, and I use 1 ml for 20% water change in 75l aquarium.

Efficace mais bouteille abimée
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.

Indispensable para tu agua de acuario
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.

Reliable and good value
I ordered the 250 ml Seachem Prime mainly for convenience and because the price was about the same as my local store. I’ve used it a few times now for water changes in my aquarium, and it’s been great — no problems at all with the fish. The product has a strong smell (kind of sulphur-like), but that’s totally normal for Prime and goes away quickly once it’s in the tank. I like that it works fast and only needs a small amount each time, so even a small bottle lasts ages. It’s definitely one of those essentials that makes fishkeeping easier. Overall, a solid choice for anyone who keeps freshwater or tropical fish and wants a trusted, effective conditioner.

Sehr zuverlässig – ideal für Aquarienwasser
Ich benutze Seachem Prime regelmäßig bei meinem Aquarium und bin sehr zufrieden. Das Produkt entfernt zuverlässig Chlor und Chloramine aus Leitungswasser und bindet schädliche Stoffe wie Ammoniak. Die Dosierung ist einfach, das Wasser wird schnell sicher für Fische und Garnelen. Auch bei Wasserwechseln oder Neueinrichtungen hilft Prime, das Gleichgewicht im Aquarium schnell wiederherzustellen. Für alle Aquarianer, die Wert auf gesunde Wasserbedingungen legen, eine klare Empfehlung.
