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

Love using this with for my aquarium. I have a freshwater aquarium, so I am not sure how well it works for saltwater. Hopefully, I will have my saltwater aquarium set up by the end of the year. I do recommend this for freshwater aquariums.

Great product but the bottle cracked on a seen when I dropped it on carpet

It was suggested to me and seems to do as it promises. Water peramiters stay where they should and coral and fish are happy

Love this stuff! I use it for all of my tanks and wouldnt use anything else. I love that its almost impossible to overdose and I feel its reasonably priced.

Prime works like a charm. Smells but does go away quickly. No fish has ever died in my tank from ammonia or nitrite. Helped me out when having level issues and while stability kicked in. Love seachem products

This conditioner after opening for a while has a very strong stench. It does the job but when you open bottle it smells like chemicals

Best de-chlore and water prep. I wouldnt use anything else.. in fact I dont put any other chemicals in my water.

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!!

Have been using this for over a year - does an excellent job for setting up new tank and water changes. Recently I ran out and used another product when I changed water. Lost a fish!! I will always use this from now on. Excellent readings (spot on) for Ph and Ammonia/NItrates when using this.

This stuff really does the trick. Im running a 30 gallon tank with two baby koi in it. Now I know thats very bad because they grow super big but thats why Im upgrading the tank when they get larger. But let me tell you right now, this stuff REALLY makes the tank clean. It can be used for anything! Conditioning the water, emergencies, even just cleaning the tank! It really is a multipurpose item. Get it.
