Hi,
I'm using it in one of my tanks. Aqua Medic's own advice is to top off with a fine gravel if you intend to keep bottom dwellers such as Corys as the gravel is quite sharp. I put a couple of cms of a fine black gravel over it.
As it's only been running six weeks I can't comment it's efficacy as a substrate but everything seems to be growing in OK.
