Finding black sand: suggestions and recommendations

[barnicle]

I was thinking about the seachem flourite, but I got warned it might be too harsh for Cory's. Since my tank probably won't have them, but you never know what the future holds, I'm looking for alternative black sands.

I came across the Froghouse black aquarium sand on Amazon - no link from my phone, sorry. Seachem also has a black clay "gravel" that caught my eye.

If I decide to add Cory's down the line, I want to know what safe options are out there for them.

That's a shame, I've had good experiences with limpopo. The Aussie sand you've found might work, though it's frustrating when sellers don't include product images to gauge grain size and texture. If you're not planning to plant the tank, I'd steer clear of anything with added nutrients – it's just asking for trouble.

After doing a quick search, I found that the garnet sand options I came across were either sandblasting media with sharp edges or tumbled stones that were pea rock size or larger, which were quite pricey and not the right size for my needs. I suspect that a lot of the price hikes we're seeing in sands are due to shipping costs, both globally and locally, given that they're heavy items to transport.
