Remove Chlorine and Ammonia

The simplest water treatment for tap water to make it safe for freshwater aquarium fish and plants. Very reliable and effective in removing ammonia and chlorine with very small amount of Prime for each 10-gallons of fresh water. Will last a long time of frequent water changes. Does not contain copper and safe for planted aquarium or shrimps.

I rely on prime for safe, easy, and effective water treatment. I have a small freshwater tank, and prime is the only treatment I use. I have been using it for years. I would never want to be without it.
