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.

Fluval 12579 First Impressions

"Super saturated color."

She wanted to bring a jar of 100 marbles to school to celebrate the 100th day. I just rinsed them with hot, then cold water, and put them in the tank. I recieved 8 though two were smaller than the rest. Natural-looking and don't seem to affect tank parameters. Otherwise works and looks wonderful. But that is not a flaw with the product, as the marbles are very nice. They looked so good I bought more for other bathrooms.

"Good size."

Awesome love the price and the color. They were exceptional however they were to small for what we needed! Otherwise works and looks wonderful. So, very pretty, glow nicely at night and add a pop of color during the day. May sound strange but I do happen to have a bee hive in a tree in my back yard. One thing I can say is 200 pieces is only good for a 5 gallon tank. They look beautiful, glistening in the sunlight, too.

3. Galapagos 05132 Sea Glass for Aquarium, 4 lb, Frosted White

Galapagos 759834051329 First Impressions

"Nice product."

The bees can get water without falling in. The glass isn't cloudy, the sizes are uniform and you get the weight described. They were clear and seemed identical. The sizes were about 3 inches diameter for most stones, and one small one thrown in. They were exceptional however they were to small for what we needed! It would take ten bags or 1,000 marbles to fill the½ gallon jug¾ of the way. I read the other reviews about not 100 pieces.

"How enchanting!"

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. These marbles were purchased along with the 100ct Panacea Lustre Black Marbles. They look beautiful, glistening in the sunlight, too. Described as aquarium stones but I used them to decorate my plant pot. They're big enough to hold stems in place and allow water to fit between them. The marbles are perfect for floral arrangements in glass vases.

I bought these to use a Awesome Points in Cards Against Humanity. Used for centerpieces at my wedding. I use them in a vase to help with arrangements. May sound strange but I do happen to have a bee hive in a tree in my back yard. My goldfish began to eat the sandy gravel so I purchased this gravel. These gems are so dainty and sparkly! Wish I had done this a long time ago.

"Nice clean look to them."

Definitely not the case with these. The water is very clean and therefore less maintenance required. The only downfall is the amount you get. Really great color and looks nice in water. Making glow in the dark, concrete stepping stones! Good for the tank with the added bonus of looking good too! I ordered two of these for my 75 gallon tank.

"I love them."

Also, they have been in my tank for about 5 weeks now. Gorgeous stones, I highly recommend! I'm gonna order a couple more bags of these just because I know they work. There has been no adverse effects from the rocks. I do plan on purchasing more for my other fish tank and my succulents. Making glow in the dark, concrete stepping stones! I only bought one bag at first and loved them so much that I bought two more.

"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.

6. Zandobbio Natural Marble Pebbles, 3 lbs

Quartz Colors First Impressions

"Work great."

Great for my betta because he cannot snag his fins on them. These marbles are as good as marbles can be. The stones that I got were even better looking than the picture. These gems are so dainty and sparkly! I ordered two packets and counted them one by one. So, very pretty, glow nicely at night and add a pop of color during the day. We use them to decorate a gravel garden path until the birds steal them all.

Quartz Colors Final Thoughts

"Work great."

The bag they were in protected every single glass drop inside. I'm using them in a tank with black sand and green plants and they look very nice. If the rocks were a little heavier then I would give it 5 stars. But now that I have them I absolutely LOVE how they look in my tank! Looks very nice is my little fish bowl. But that is not a flaw with the product, as the marbles are very nice. They're big enough one package goes a long way.

Penn-Plax First Impressions

"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.

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.

"I purchased a 2."

I used these stones in my bathroom sink and they are beautiful. Great quality, though smaller than I thought. Used in a terrarium with a bonsai tree. My little guy loved these they are the perfect size for his little tank. I just rinsed them well before putting in my new tank. 500 marbles isn't as big a bag as you think, but they're all there. These marbles were purchased along with the 100ct Panacea Lustre Black Marbles.

"Could have been better."

I was very pleased and my daughter was, too! Also, they have been in my tank for about 5 weeks now. For a sample compare the advert photo and the darker photo from the reviews. Reviews say not to clean them when they get dirty so I won't. Light casts through them well and they are attractive. Its a small bag of rocks, cant really mess that order up. So, very pretty, glow nicely at night and add a pop of color during the day.
