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

If you are looking for a water conditioner for your aquarium that will not break the bank, then your search is over - this is the one for you. 1ml of this liquid will treat 40l of water and you can use this in an emergency if you have an ammonia spike, as you can add up to 5 times the usual dose. The only downside is that when shaken sufficiently it smells like all of the rotten eggs you have ever smelt.

Did what I needed

always keep plenty of bottles on hand, only de-chlorinator that removes nitrates and ammonia. been using for 5+ years. one capful = 55 gallons

fantastic and fast service and does the job as it says thankyou

Use this regularly to keep my 30 gallon aquarium stable.

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

It`s working fine.

Ivd used this priduct for years on all my tanks, at every water change, and its great! For smaller tanks, just make sure you have a measuring syringe, as you only need 0.1 ml per gallon (even emergency doses are only up to 5xs that).

When my local large conglomerate pet store decided to stop selling any kind of decent sized water treatment, I turned to the one place who I knew would have it for a deal.

Been using this for years
