View Full Version : Prime question
I was changing the water in my tank and I noticed that there was a lot of black things floating in my bottle of Prime. It also smelt really bad. I was wondering if this was a carbon additive or something else? Thank you

Black specks in Prime are completely normal and in no way degrade the product (they are actually an excess of ingredients....this is a very concentrated product). The sulfur-like smell is perfectly normal as well.
Ok, thanks for your help.
