I have both crushed coral @$30 per 50lb bag and playground sand @$2.97/bag. I'll say the crushed coral is very white and looks good. Playground sand is good, but seriously consider pre-rinsing it very good before putting it in your tank, as it will be really cloudy for a while, and every time you re-arrange anything.
if you can find ceramaquartz or spectraquartz, both should be great. I have colorquartz (discontinued) and it's a great substrate and I only paid 23$ for 50lbs.
I went with the smallest grain.
