I use Prime all the time on my tanks and I love it. Mostly concentrated prime, right? Use 2 times less per volume than stated, right? nope! This is the same as Prime which is designed for use in the pond. They believe that since your pond has more surface area to outgas, you don't need to use as much product to get the same dechlorination benefits. Most likely yes, but then you are not using it according to the label directions in an indoor aquarium! Search the Seachem forums and you will find the same information from Seachem representatives. I am still a Prime/Safe user but very disappointed with how this marketing/labeling took me. Buyer Warning!
