The only problem with those sands, is that 'forest fish' like dark substrates... play sand and filter sand are usually bright.

If you have a pool supply company nearby, call around and try to find 3M Colorquartz in S grade. It's used as a liner in swimming pools, but it's totally inert and safe for aquariums. (Be sure to wash like mad, warm water helps. No worries, it's just dusty.)

They won't say it's safe for aquariums because that's not what it's made for. It's actually quite ironic...
When the aquarium people realised how great it was, they started a petition for 3m to sell it in smaller quantities. 3m said no, discontinued the product (although it's still available in some warehouses), and now Estes makes Reefsand, which looks eerily similiar...

BTW, colorquartz is $12-$24 for a 50-pound bag.

Thanks for all the replies, you've all been really helpful. I decided to go with play sand and see how it works out. The process of switching is taking a really long time tho haha
