Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 500 ml

This is a must have for any fish keeper. I always keep this in the fish room!!!

The best water conditioner ever. It lasts ages because 2 drops of it treat a gallon. It also temporarily removes ammonia from the water!

I ordered my first one in March then recently ran out so I ordered more. I ordered this new one 2 days ago.It came in perfect condition no leaks no scratches. Though, the only reason I gave it a 4/5 is because the labeling was different from what I ordered in March. It worried me but it seems to work the same. I guess they just updated the label they out on it. Otherwise, I still loves this product and my Goldfish are still healthy & hungry little buggers. :))

i decided to try this line of aquarium products because after reading the literature on it, it seemed the more innovative direction to take in striving for creating optimal turtle tank conditions. i have had great results with seachems purigen, which is a re-chargeable substitute for carbon in your aquarium filter.....if u inow turtles, they are very dirty and consequently, i was spending a great deal on carbon, which is really just a throw away after one use. anyhow, the prime product is used when u do water changes and when i first saw the size. the bottle, it seemed so small until i read the instructions....you only use a teaspoon for 50 gallons. the combination of the seachem products is resulting in better test results on my ammonia, nitrite and nitrate levels and i dont have to do as much maintenance on the filter and the tank it seems. i would heartily recommend this product and plan to continue on with ordering items in their line!!

This is the only product I use and I cant imagine raising fish without it! There is nothing on the market like Prime...ask anyone that raises fish and youll get the same answer! Theres not much more to say...its the cats meow and the fishes tail! Dont attempt keeping fish with anything else...youll be sorry!

I have been using this almost since the beginning of my interest in the hobby. This is the single most important additive you can have on hand as a fishkeeper.

I always use this on my 75 gallon tank when I do water changes. Last week I forgot to add it and when I looked at the tank 5 minutes later, half of my fish were laying on the bottom, almost dead form the high chlorine in my tap water. I immediately dosed the tank and within 5 minutes, they were back to normal and looking for food. I won’t ever buy a different product. Prime is unbelievable!

This is wonderful product I have south american and African cichlids. Works great a must need for cichlids. ....

Works like its supposed to great product I love this brand love buying it from Amazon great value

Cleared our fish tank up within a couple of days. Our fish tank really needed this! We got it fast and super easy to use. I got recommended this product and would recommend it for every fish tank!
