Black Beauty, sand blasting sand/media sand is black, it is a larger grain then most sand so it doesn't get sucked up into my filters as easily. And it runs about 10.00 USD per 100lbs
I'm thinking of slowly converting my gravel tank to a sand tank, as theres no fish that benefit from the gravel and I think my Khuli would be happier with sand, but my one question is, how do you vac without the sand going up?
Mine varies from about .5"-2.5" in the deepest part. It's a brand-new tank with no fish in it yet, but the dept probably will change when I add my fish.
