"I love it."

The glow is pretty minimal but it still looks nice. I filled with filter water ad let sit for a day before relocate fish. Really like the coloring of them as well. There's a nice mix of color and gives my little nano tanks a nice earthy feel. A little bigger than what I wanted but I still used it. I have a 90 gallon aquarium with a footprint of 18 by 48 inches. I'd recommend but just be wary of debris.

"Great product."

I didn't even need the water clarifier, and I found it in the bag. Just make sure you rinse it out REALLY good, before adding to your aquarium. I half rinse it and put it in my tank. I used these to put on top of soil if my pot plants. Love the vibrant neon colors mixed in with the black gravel. Don't even waste your time adding it to your tank.

"I haven't used this yet."

Don't own a blacklight so can't tell if it glows or not. This gravel works extremely well for planted tanks and for smaller fish species. Really just rinsed a little and ready to go. I didn't even need the water clarifier, and I found it in the bag. I have a 90 gallon aquarium with a footprint of 18 by 48 inches. Just do a proper rinse, and you will be fine. Don't use any soaps or anything else.

"It's just what I wanted."

This was the cheapest DIY project with a big wow factor. I did rinse it off before putting it in the aquarium. For smaller plants, these rocks are a little on the big side. This is the real deal mother earth approx. Snails and fish dont seem to mind the switch from sand. I've been using that for a few months now with my betta. Secondly the gravels colour looks enhanced under a bright led light.

"So little by little."

I've been using it now for a couple of months and nothing has happened to them. Worked great for my succulent gardens. This was because of my own preconceived notions and not that of the sellers though. One bag was open and had emptied into the box. Although I had to rinse it about 5 times to fully get ALL of the dust out. I filled with filter water ad let sit for a day before relocate fish. Really like the coloring of them as well.

"Nice big bag of gravel."

At this point I'm Trying to wash pebbles. It comes in a variety of colors, but I prefer the classic white. The color mixture with the darker colors in it does that very well. It will take you a while to properly clean. It does need a good washing, and I used a 5 gallon bucket method. Wonderful mixture of color with the black stone. It worked really well and still allowed new stems to pop through.

There's a nice mix of color and gives my little nano tanks a nice earthy feel. The gravel size is exactly as described in the product description- 2 to 4mm. Although I had to rinse it about 5 times to fully get ALL of the dust out. We bought this for a glo fish tank. Secondly the gravels colour looks enhanced under a bright led light. I use a hybrid of the Walstad Method, and this stuff is perfect. The little package of clarifier included is not nearly enough.

"These are perfect."

Arrived in 8 sealed plastic bags inside one Priority box. For smaller plants, these rocks are a little on the big side. I also found a DEAD spider in the gravel! This is my favorite gravel I've bought from Amazon. This is my favorite gravel I've bought from Amazon. Had to move fish out after it nearly died.

"Fantastic gravel!"

Obviously required a lot of rinsing. Not sure why there is so much bad feedback for this. Aside from the size, the appearance of this gravel is what stands out the most. The texture is smooth so cories and burrowing fish will not hurt themselves. I'll definitely use this gravel again the next time I start a new tank. 5 inches of gravel, so you could use more or less depending on tank size. It has lovely colors and I will be using ONLY this gravel in the future.

"Just as described."

It's my new, absolute favorite substrate. I used these to put on top of soil if my pot plants. We bought this for a glo fish tank. I have a 90 gallon aquarium with a footprint of 18 by 48 inches. The color of the gravel makes the blue in my Tetra's and Gourami's pop. Needs more plants but it makes the colors of the fish and other decor really pop. It really makes the tank look sharp and I believe the goldfish likes it, too.

"Nice product."

Secondly the gravels colour looks enhanced under a bright led light. Just be patient and realize that it's going to take a while to rinse it. Don't own a blacklight so can't tell if it glows or not. I used this for a path in a 22 gallon aquarium. I used this for a small aquarium with 2 goldfish and it worked great! It smells like chlorine and epoxy glue. I bought two bags for my 55 gallon.

We bought this for a glo fish tank. I didn't even need the water clarifier, and I found it in the bag. I've been using it now for a couple of months and nothing has happened to them. Removed pebbles and refilled for the 3rd time. Yeah this stuff has to come prerinsed. Not sure why there is so much bad feedback for this.

"Love this blue gravel!"

The color mixture with the darker colors in it does that very well. I didn't even need the water clarifier, and I found it in the bag. I also found a DEAD spider in the gravel! Water became with film like on top and lots of little bubbles on every surface. The gravel adds amazing color and the fish and snails seem to like it. We bought this for a glo fish tank. All n all, very happy with the purchase.

"Looks great."

Works great in my daughter aquarium. I used this for a small aquarium with 2 goldfish and it worked great! I've been using that for a few months now with my betta. This is perfect for a 2 gallon tank that also has some acrylic gems. Really like the coloring of them as well. It looks great and didn't change anything about the water. It was easy to clean and looks great in my bamboo glass vases!

"There is none."

Everyone ask where did i get that color. For my purpose, they work perfectly, for an aquarium, they might need a quick rinse. Using these stones for growing bulbs for church project. I was scared to buy it after the reviews I read about it killing their fish. I found it easier to do a medium sized bowl at a time. I filled with filter water ad let sit for a day before relocate fish. If you have to bury tank decor that doesn't have suction cups then you need more.

"Held its color when wet."

I bought a few bags of this and it's nice. They served their purpose, but had to be the dirtiest rocks I have ordered. This was the cheapest DIY project with a big wow factor. Don't even waste your time adding it to your tank. Just do a proper rinse, and you will be fine. But the gravel itself is nice quality and adds interest to tanks. Out of the bag there is an amazing amount of dust.
