Geosystem River Black Fine Gravel

Hi! I just bought 4 bags of this for my planted tank, has anyone used it? what cons and pros? It's quite hard to find cheap black substrate, so I decided to have a go..

Im sure it will be fine if it's fine gravel. It will say on the packaging if it alters the KH. You might want to add some sort of plant substrate underneath it, like the tetra brand one or the tropica.

After a long day of mess it's finally in the tank! it looks very nice and not expensive! I think i does alter kh, but I haven't checked and I don't mind as kh in my tap water is only 3kh, i recommend it to anyone, who wants a nice dark substrate!
