Dark or black substrate suggestions? Cory friendly.
I'm looking for suggestions for a dark or black substrate. I now use MGOPM capped with natural creek gravel found locally in most of my tanks, but I'd like to try something different in a tank that will have Columbia tetras, Diamond Tetras, and some type of Cory in it. I haven't even come close to picking out which cory, so that's up in the air.
The plant selection will be almost entirely needle or narrow leaf java fern and various anubias. Also, this is for a low tech/low light 90g tank. Normally I prefer a natural looking tank, but I think I'd like to do one with a little drama - hence the light fish and the dark substrate and limited plant selection. (to be honest, it's just that those are my favorite plants - lol).
I have Midnight Black FloraMax in on my 40B, and the color is leaching into the water column after 4 years, so I don't want it again. I've read about the blasting sand, but I worry that it's not appropriate for the corys. Are there any rounded, gentle to their belly/barbs options? I recently read a suggestion on another thread about going to local quarries and seeing what rock they have (because it isn't dyed) and I'm going to do that. Fortunately there are a few close to me. Still, I'd like to hear what others have found and are using...
An after thought; does anyone know how slate affects water/fish? I was even thinking about having about having a local quarry cut me a slab of slate to fit into the bottom of the tank. Like the old slate bottomed Metaframes. I'd like the look of that, and it would be so easy to clean (I don't plan on planting in any substrate on this tank). Well duh, I guess slate would be too rough too, don't know what I was thinking...
