Hi Stephanie, no, I think you misunderstand me, – or maybe its the word spagnum which means something different. I google translated it, and of course the right english word is peat. Heres a link where you can find it down on the page named ‘peat’.

Killi breeders use it a lot for breeding tanks, – you just put a small amount of it, and it lies at the surface for a few days, then sink. It has of course to be the kind thats specially for aquarium purpose.
