So here's my experience so far:
the sand was very heavy. It definitely does not reflect light so the tank looks a little darker. I wanted white but when I checked out the white sand from the same company, it was literally like flour. I thought that might be too fine. However, I'd heard this tahitian moon was quite sharp and it was a bit while dry but when i added water, i was comfortable running my hands through it without any issue. I rinsed it a bunch first and then i soaked it for about 2 minutes in boiled water ( i boiled it in a pot, then poured it over the sand and stirred.) it's in the tank now and i'm waiting for the heat to go up before I put crumb back in. I woke up at 3 am so worried i was going to kill little Crumb!! I'm a bit nervous... update to follow.
