Glow in The Dark Sand, 17.6 oz Mini Glow in The Dark Rocks Fish Tank Sand Aquarium Gravel Glow Pebbles Luminous Stones for Garden Driveway Gap Filler Wase Potted Plant Sand Art Bottle Decor (Blue)

These have a great glow to them

20 dollars for a tiny little bag that will not even cover the bottom of my fishtank. Is not sand, like it claims. Total waste of money, never again!!!!!! I'm second guessing whether I will even buy anything from Amazon anymore, total rip off

This is perfect when used as a night light for your little ones. Just a few minutes in the daylight and it will glow for hours in the dark. Black light wasn't needed.

The stones float in the fish tank. Their glow is amazing, after they get sunlight, which was super awesome to see!!When I cleaned the tanks, holy moly, they clogged every cleaner I had. Ruined 2 of them. Pain in the neck. Needless to say they are gone now.

I love the look in my aquarium. And the packaging was perfect

I didn't check the size of the bag. I assumed that it would be enough for a tiny fish tank and it's not. It would probably take about 8 bags. Also, most of them float and I had to push them down. The glow aspect is cool though

Don’t bother it only would light up for a couple hours after being in direct sunlight in summer for the entire day. Then stopped working after a couple hours.

Not what I expected but they do glow
