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

Excellent product. All round good

This is honestly the best value for money water conditioner I have used. It lasts a long time because of the high concentration. I now have 3 goldfish tanks on the go so I’m now buying the larger bottles.

Great dechlorinator. A little goes a long way. Was cheaper than any local store to me.

I love seachem only brand I try to stick with. I live in a tiny little town that has one small pet store and the store owner thinks he can charge people $95 for 1L of prime!!!!! So trust me when I say this is as good as chlorine removers get!!!

Blocks ammonia and nitrites for 24-36 hrs takes care of the chlorine and cloramaines

The best water conditioner money can buy. The fish are happy and so am I.

El producto ha llegado completamente destrozado y no tenía pinta de ser del transporte sino de que ya venía así

Great value, just can be hard to figure out dosing for small aquariums.

Came fast as expected seachen prime good quality.

The product i got was not sealed, it smells nothing like the bottles i have had in the past. I am pretty sure it is diluted, ive lost 3 fish in the past 2 days since i started water changes with this bottle. Not sure if its the cause of the prime but i will be getting my water tested and buying a new bottle.
