Pricing per Home Depot web site:
Play sand (4 different kinds) 50 lbs for $4.57
Pool Filter Sand 50 lbs for $5.98
Play sand costs 76% of the cost of PFS, not 75% less.
5.98 x .76 = 4.54
75% less than 5.98 = $1.50
...and by the time you spend all that time and water rinsing it, you have washed away a lot of it, it becomes more expensive.
