Fish Herder
From the data sheet, it looks like pure ammonia, but I'm not sure. If it was me, I'd wait for someone with knowledge of products in the UK to answer, just to be sure. Unfortunately, I've never had to do a fishless cycle. All of my tanks are clones of my old tank. I just got a 75gallon and was concidering doing a fishless cycle, just so I could say I've done one, but I'm not a very patient person. Cloning has always worked for me. By the way, Great job on doing your research before you get fish!
