    Works great. Not all the pet stores carry this. Glad I found it on Amazon.

    my hermit crabs are still alive,so I am guessing it works. Exept every time I pour it, it stinks.

    Prime and Stability. The only products I ever need to add to my water. I even use Prime to lubricate bio wheel bearings and as a stress coat in my hospital tank

    Great product. Buying in bulk is better imo instead of several of these bottles every few months.

    The only dechlorinator I will use. A little goes a LONG way and I wont even order the big bottles anymore because the little ones can last so long. My favorite Seachem product on the market. Reliable, perfect.

    Zero packing was used in shipping, literally a gallon jug in an oversized cardboard box the bottle leaked and the lid was coming off when I opened it.

    This is great to use during water changes. The only downside is that it smells horrible. It smells like a skunk The smell fades but its pretty strong for a good 30 minutes after using it.

    I love how concentrated it is. Saves me a lot of money in the long run since I have a lot of water I need to condition weekly.

Seachem Prime is a complete and concentrated conditioner for both freshwater and saltwater fish tanks, working hard to remove chlorine and chloramine.

For over three decades, Seachem has been a company rooted in sound science.

Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by
hobbyists. All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such passionate hobbyist - Dr. Leo G. Morin (Founder) - recognized that the available solutions to aquarists problem wanting. This resulted in Seachem’s very first product: Cupraplex (today known as Cupramine). Over thirty years later Seachem is still approaching old problems in a new way.

Seachem’s philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.
