I currently have black flourite capped with a light gravel in my tank that is cycling (no fishies yet). I've been humming and hawing, and made a bad unplanned attempt at removing the gravel. But I have decided the yes, I want to remove the gravel (before things get too settled in), and I want to recap with black sand. I was thinking flourite black sand, but that's another $30. I'm just wondering if there are any other less expensive black sand options? I've heard of black blasting grit, but I'm not sure where I'd source that in Canada. I'm planning on doing this on Friday, so I need to find something before then.
Any suggestions? If I can't find anything else, I'm fine with the flourite, but it seems every time I turn around I'm spending another $30
