Yes I've done it countless times. With fish I'm the tank it'll be fine, I've used a smaller bucket to place the sand on the bottom rather than just dumping it all in at once makes less of a mess (not much less) and watch to make sure filters are off and I suggest running just a sponge filter for a couple hours if you can. With play sand rrinse rinse rinse rinse and rinse then after rinsing rinse.

This is my filterPlay sand can be dusty, but the main problem with play sand is it is very light and has fine grains that are easily stirred up. These fine grains can flow freely with the current in the water column and get into your filters, and ruin impellers. The reason many fish keepers prefer pool filter sand, is it is heavier and the grains are a little larger thus, can not get in and ruin filters as easily.
