Alan Stone Glow in The Dark Home and Garden Fish Tank Aquarium Decorative Sand Gravel Rock (3-5mm, Blue)

N/a

Love it looks really pretty in our fish tank

I certainly don't recall seeing the quantity listed anywhere before I placed this order; I'll deem this experience as another opportunity to have learned a lesson about fine print, sizing and amounts regarding whatever product is at hand. The number of pebbles I received in exchangefor $16.99 was a little bit shocking. I thought it would be an aquarium gravel smaller bag like we've all seen elsewhere online or in the petstores. It was nowhere close to that, but actually arrived in a container the same size as the other 5 containers I have next to my hermit crab habitat, which hold food, treats, sea salt, and calcium powder for shell health. I've now triple-checked that I actually paid that much for a sprinkle of rocks, and tis true. 😩🤑👻💩🙀 Glow rocks: an expensive addition to a sweet aquarium or terranium pad made exclusively for the elite fish and crustaceans in the world.🫢

Didn’t glow very much

Looks awesome however once you clean the fish tank, this stuff gets mixed in too much with the gravel and you can't see it anymore! You would have to purchase like 5 or more of these to keep seeing it every time you siphon the gravel! Looked beautiful though before I cleaned the tank. Now I'm lucky to see one or 2 glow rocks. Purchase a lot if you want to keep seeing it in the tank!

Don’t change anything

These rocks stay lit for hours. I use them to make my prosperity bottles. And Inlove going to sleep looking at them.
