Prime, 100 mL / 3.4 fl. oz.

It does a great job on treating tap water.

The smell of this stuff is not great, but goes away after the water is treated.

This stuff really works! It does have a small foul odor to it, but it dissipates soon enough. It only takes a day or two for this stuff to work it's magic on high levels of Ammonia and such. My water is crystal clear and my African Cichlids are happy. Two thumbs up!

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 seachem's 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 don't 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!!

Used it since i started a new tank, works well. The ammonia feature works somewhat, it seems to improve the fish coat. Removes chlorine well never had a chlorine problem while using this.

Must have product for all aquariums!!! The label / bottle might not look as appealing as other branded aquarium pharmaceuticals (ie. TetraFin etc.) but the product works wonders. One thing for sure is, when using this product you might show false positives in your test kits, however, do not be alarmed if you see high Ammonia / Trite / Trate readings, this product simply detoxes these for up to 24-48 hours to make it safe for fish. To get proper readings, just perform water changes weekly.

Just as a tip, I use Prime to help me with my fish in cycles.

NOTE: FISHLESS CYCLES ARE ALWAYS RECOMMENDED, IT IS LESS CRUEL FOR THE FISH AND WILL GIVE YOU AN ADDED BENEFIT OF FULLY STOCKING AN AQUARIUM.
