There is a faq page on the website but it only seems to cover the white play sand. Also its pretty expensive there is a calculator, I used it to see how much of their floral sand was needed for a 2" depth on a standard 180 it said 190lbs. 25lb bag is $33.00 + $15 shipping/bag $48.00×8 (8×25=200) $384.
Cant find anything about what is used to color the sand or the colorfastness of it.
Ive emailed them in the past and I dont believe I got a response. It coulda gone to spam. In the mean time while waiting I did the math and decided it was to expensive to persue.
Would like to see pics as well and if anyone has used it for a while.
