Anyways, 2 options for now are black diamond and pool filter...just have to decide what look I want to go for; natural, black.
I am putting soil under this so even though I prefer natural, I'm worried that itd look tacky being tan over black. Plus black would make everything pop more, but worried that it will become to dark with black substrate and black background

Play Sand is better/safer for corys. I have 3 inches of Quikrete Play Sand in my 5-foot 115g tank, with almost 40 corys now, all wild caught and some larger fellows, and I never have problems. The filter intake should be 5-6 inches above the substrate anyway, so that is not an issue.
Some pool filter sand and some blasting sand and all paver sand is rougher, and not a good idea with corys. Play Sand is almost identical to the sand in Amazonian streams, so you can't get much more authentic unless you went down there with a couple of buckets and brought back some sand.
Just a note on black substrates. I tried this, and didn't like it. Every speck of stuff stuck out. I never see stuff on my sand substrate tanks, nor my fine gravel tank. I have the "mix" in all of these now, and Quikrete Play Sand is ideal for this.
