  • Great product
Great product, I order reorder this product a few times for my fishes. Ease of use, helps water quality, and nitrates

  • Deserves the hype!
I prime my water with this every cleaning and have never had any problems. However, do be careful, I was adding this to my water every day when I started the tank, hoping to combat any ammonia/nitrogen spikes, and you CAN overdo it! I was advised on the internet that this was perfectly safe at well over the label instructions, and that is NOT true. But that wasn't Prime's fault, it was mine for trusting the internet. At any rate, it is a great product that, when used in accordance with the label, is safe and effective. ... show more

  • Works!
I have beautiful, living fish! I am not an exact scientist and do not usually measure, therefore probably use too much and waste it.

  • The go to conditioner
Prime is best on the market . It’s instant and you don’t have to use a ton of it to condition your tank . Always put it in before you add new water . It also helps keep nitrites and ammonia to a minimum. Def recommend it

  • A must have for any aquarist
I had to set up an emergency tank and do fish in cycling and prime kept everyone safe and alive. It's more concentrated than other brands so it is a better value. I keep it on hand for water changes and spikes. I also use when adding new fish to combat ammonia spike dangers.

  • Smells like death but prevents fish death!
Great staple product for any fish keeper. The product itself is on the pricey side, but it does last quite a while and I know that my axolotls sensitive skin won't get burned by this conditioner. The stuff smells like death, but it's worth it for the water quality.

  • Fish approve
Been using this for years. Never had an issue. It sticks like sulfur as the bottle gets older, but it works good and my fish are healthy and happy.
