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

NOT HAPPY AS IVE JUST OPENED THIS TO USE AND FOUND BLACK STUFF FLOATING INSIDE. BEEN ONTO THE SEACHEM WEBSITE AND THEY SAID IT HAPPENS IN OLDER STOCK,

As described

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

Never do a water change without it!

This is the best water conditioner on the market. It also converts toxic ammonia to non-toxic ammonium. But if your test kit only measures total ammonia you wont see the change in values - you have to buy a special ammonia kit to separate out the two types of Ammonia. As an overall water conditioner there is none better. Just remember you dont need to use too much (its very expensive) to get it to work but I know most of us want to be 100% safe. Works nearly instantly to remove chlorine.

Good product at a good price

This product works great for my axolotl tank.

I’ll always buy this product A++++

This is the real deal with the same sulphur odor, size delivered as described - and about half the cost compared to local retailers.

Of all the similar products on the market this one is the best.
