なぜか他のを使うと金魚がめっちゃクレイジーになる。これだと普通に泳いでる。何が違うかわからんが。

何回かこの商品を使っています。注文から商品受け取りまで敏速な対応で商品も非常に効果が有り気に入っています。今回は箱を開けてみると、商品の蓋が着いてませんでした。液漏れはしてない様なので幸いでした。前回購入した時の同じ商品の使用済が未だ手元にあったのでそれの蓋を取って使います。 いつもは星は5なのですが、今回はこの件で3にしました。

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.

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.

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.

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.

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.
