Castuvy First Impressions

This is really neat.

I have purchased a few packs and every pack is different. Really pleased with everything related to the item! Great quality, though smaller than I thought. The sizes were about 3 inches diameter for most stones, and one small one thrown in. They look good and should serve their purpose well. My goldfish began to eat the sandy gravel so I purchased this gravel. All arrived clean and in good condition.

Castuvy Final Thoughts

5 retreat tank.

I've read some other reviews where some other brand glow rocks hardly glowed. I have included two photos of the ones I received. I've read some other reviews where some other brand glow rocks hardly glowed. There isn't much to say, other than this worked for its purpose. I used mine to start filling a glass jar that used to hold coins. Noticeable improvement in the clarity of the water. I painted targets with large used pizza boxes and they were used with the marbles.
