Seachem 437 Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 1L

Always used it with no issues....

Use this every water change.

Prime is awesome for removing chlorine from your tap water. I use it for my freshwater tanks and also when I bleach my saltwater filter socks. Second soak gets a prime dose.

Does the job good

Great product! To bad that packed not so good, two bottles out of three was opened from the transporting.

This is a miracle product, especially if your tank is uncycled or in a mini-cycle. Prime saved my fish from ammonia spikes on more than one occasion. It also removes chlorine better than any other product Ive used before.

Great for neutralizing bleach when cleaning filter socks for a saltwater fish tank.

Use this for all my tanks and this size last me a very long time well worth the money.

I’ve used this for years and no dead fish.

Huge bottle for $20 its the best deal anywhere!!! Highly recommend!!!!
