"They are glass."

There has been no adverse effects from the rocks. One thing I can say is 200 pieces is only good for a 5 gallon tank. The price is a bit shocking at first, but the rocks are nice. 500 marbles isn't as big a bag as you think, but they're all there. Worked well for what I needed them for. 2 tanks have a betta or corydora catfish so I needed smooth rocks for their safety. Light casts through them well and they are attractive.

Penn-Plax Final Thoughts

"Works well."

Nice and shiny giving that always wet look. So, very pretty, glow nicely at night and add a pop of color during the day. I ordered two packets and counted them one by one. Great quality, though smaller than I thought. I just rinsed them with hot, then cold water, and put them in the tank. These gems are so dainty and sparkly! Described as aquarium stones but I used them to decorate my plant pot.

"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.

"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.

"I love these beads."

I am using them in a shallow pan with water to let bees drink. One thing I can say is 200 pieces is only good for a 5 gallon tank. Wish I had done this a long time ago. All arrived clean and in good condition. 500 marbles isn't as big a bag as you think, but they're all there. If you are ok with the price, they are really pretty. Reviews say not to clean them when they get dirty so I won't.

"Perfect for aquarium."

Just an FYI, the white sea glass does not stay white, but still looks lovely! I bought these to use a Awesome Points in Cards Against Humanity. They look nice mixed with light brown sand. Gorgeous stones, I highly recommend! They look so beautiful in my 5 gallon tank. I have purchased a few packs and every pack is different.

"Looks great."

To be honest I am debating ordering a third package. But I feel that's only if your planning to use them outside. I plopped one in with the shrimps and they were all over it like a tramp on chips. Out of the water they will be much lighter than their colors immersed. They look so beautiful in my 5 gallon tank. It would take ten bags or 1,000 marbles to fill the½ gallon jug¾ of the way. The marbles are perfect for floral arrangements in glass vases.

Oh well, guess I should have ordered more! Large, white stones with a smooth polished surface. Very pretty stones for the aquarium. Excellent product and super fast shipping! To be honest I am debating ordering a third package. Natural-looking and don't seem to affect tank parameters. I just rinsed them well before putting in my new tank.

"Aqua glass beads."

If you are ok with the price, they are really pretty. Reviews say not to clean them when they get dirty so I won't. They're big enough one package goes a long way. Great variety in color and size, these are going into my goldfish tank. They looked so good I bought more for other bathrooms. Received marble very fast, great marbles. One thing I can say is 200 pieces is only good for a 5 gallon tank.
