Favorite cap for soil?
I will be starting a new planted system soon, fairly large. I'm going to try a soil substrate (probably the MiracleGro-organic-whatever that people on here seem to like). This will be my first soil tank, though I've had many planted systems and other aquariums so I get the general idea overall.
I'm struggling to find a cap I like and though I'd ask here to see what people prefer. I'd like something with a bit of a grain to it (i.e. not fine sand) and dark in color, but preferably not black - dark brown or charcoal would be great. Also, it's gonna be a big tank, and I'm a cheapskate, so inexpensive is best.
Thoughts? What do you all prefer?
