Champagne, Anyone?

I’m not sure if my comments will be relevant to Chewy customers because instead of using the gravel for an aquarium, I used them to weight down plastic champagne

I’m not sure if my comments will be relevant to Chewy customers because instead of using the gravel for an aquarium, I used them to weight down plastic champagne flutes with candles inserted for my Christmas presents to my clients. Lovely colors, the right price, and swiftly delivered, as always! Chewy, you are the best!

Natural, no dye

I had looked everywhere for a natural, dye free gravel to add to my biorb fish tank. I’m always cautious using any kind of stone as some of the coating they put

I had looked everywhere for a natural, dye free gravel to add to my biorb fish tank. I’m always cautious using any kind of stone as some of the coating they put on the stone is highly toxic to fish. This stone was not only beautiful but safe!

Rocks

The purchase was gravel so not much expected..I issue there did appear to be more pieces than desired, meaning chips of gravel floating in my tank

You get what you pay for

You would think gravel is gravel but this was cheaper for a reason. There were sticks in the gravel and it was full of flat/thin pieces of what I assume is the paint

You would think gravel is gravel but this was cheaper for a reason. There were sticks in the gravel and it was full of flat/thin pieces of what I assume is the paint used to color the rocks. Not just tiny pieces but as big as the gravel. Also left color residue on my hands while I was rinsing it before putting it in my tank. Not impressed.
