Wow, nobody? I used Home Depot sand with terrific success for a 120 gallon tank that ran for about 5 years. The point is that you have to get a brand that doesn't use silica, obviously. Just picking any bag of sand is likely going to have silica.
Southdown was the brand I used in two different tanks with no issues. Supposedly the brand changed names and was available regionally. I wish I could point you in the right direction, but I haven't used sugar-sized sand in years.
