"I have no complaints."

The color looks beautiful and natural in the tank. It does need a good washing, and I used a 5 gallon bucket method. The color of the gravel makes the blue in my Tetra's and Gourami's pop. Lovely colors and everything i was looking for! I have blue lights and white lights in my tanks. I have bought 2 bags of this gravel. They are rocks, what more do you need.

  • Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs
  • GRAVEL: Seachem Flourite Black is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any freshwater aquarium environment.
  • AQUARIUM BED: Gravel modifiers such as laterite are not necessary when using Seachem Flourite Black as this product is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels.
  • SET-UP: When adding water to the aquarium, fill slowly to avoid disturbing Flourite Black substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal, but to remove this simply use mechanical filtration
  • COMPATIBLE: Flourite Black substrates will work fine with an under gravel filter and will not soften or decompose to an unsuitable state within your tank.Flourite substrates will work fine with an UGF
  • SAFETY: Seachem Flourite Black is not chemically coated or treated, thus does not alter the pH of the water. Flourite Black is beneficial for the life of the aquarium and need not be replaced.

Seachem 3725 Final Thoughts

"Held its color when wet."

I envisioned the bag being bigger since I ordered a 50lbs. If you have to bury tank decor that doesn't have suction cups then you need more. It will take you a while to properly clean. For smaller plants, these rocks are a little on the big side. But the gravel itself is nice quality and adds interest to tanks. Aside from the size, the appearance of this gravel is what stands out the most. For my purpose, they work perfectly, for an aquarium, they might need a quick rinse.

Purchased 9 bags of this for a new 180 gallon aquarium. I rinsed it before I put it in the tank. For reference, my tank is a 20 gallon tall tank.

"Love the look."

It was easy to clean and looks great in my bamboo glass vases! I'd recommend but just be wary of debris. It has lovely colors and I will be using ONLY this gravel in the future. I recommend doing it in smaller portions. It smells like chlorine and epoxy glue. The color mixture with the darker colors in it does that very well. The smooth and small pebbles are great for people keeping corycats.

"I would buy this again."

So if you are looking for bigger size, this is not it. Although I had to rinse it about 5 times to fully get ALL of the dust out. Minimal clouding gone within 12 hours. Very random shapes and colors that blend well. One bag was open and had emptied into the box. This is the real deal mother earth approx. Bigger than normal aquarium gravel, nice colors, good quality, no smell.

"I love it."

Wouldn't have any other substrate for my axolotl. 5 inches of gravel, so you could use more or less depending on tank size. I wished I would have bought a few more so It would be deeper in my tank. The smooth and small pebbles are great for people keeping corycats. The color looks beautiful and natural in the tank. I envisioned the bag being bigger since I ordered a 50lbs.

"Beautiful and natural."

I WOULD recommend buying this item! Bigger than normal aquarium gravel, nice colors, good quality, no smell. I used these to put on top of soil if my pot plants. I found it easier to do a medium sized bowl at a time. Some of the bad feedback says it clouds the water. This is perfect for a 2 gallon tank that also has some acrylic gems. Love the vibrant neon colors mixed in with the black gravel.

"About the size of."

Not sure why there is so much bad feedback for this. Obviously required a lot of rinsing. Color is good contrast to the Beta. At least any visible to the naked eye. I rinsed it about 3-4 times and felt satisfied it was good. Just do a proper rinse, and you will be fine. Snails and fish dont seem to mind the switch from sand.

"Perfect size."

Like everyone else says wash it before putting it in your tank. Just do a proper rinse, and you will be fine. I recommend doing it in smaller portions. The gravel size is exactly as described in the product description- 2 to 4mm. Not sure why there is so much bad feedback for this. I wash it in small batches in a five gallon bucket before putting it in the tank. They served their purpose, but had to be the dirtiest rocks I have ordered.

I recommend doing it in smaller portions. Aside from the size, the appearance of this gravel is what stands out the most. They're like large pebbles that are the size of your pinky-nail. I'll definitely use this gravel again the next time I start a new tank. Will definitely purchase again when needed. Perfect for the corydoras, pleasing to the eye.

"Great aquarium gravel!"

Out of the bag there is an amazing amount of dust. I was scared to buy it after the reviews I read about it killing their fish. The gravel size is exactly as described in the product description- 2 to 4mm. So if you are looking for bigger size, this is not it. Had to move fish out after it nearly died. Stir periodically and then your good to go! We bought this for a glo fish tank.

"Didn't take long to wash."

Needs more plants but it makes the colors of the fish and other decor really pop. I found it easier to do a medium sized bowl at a time. I didn't even need the water clarifier, and I found it in the bag. I am disappointed that there seems to be nothing special about this gravel. So will just see if color stays-God willing! Wash gravel well before use, and its pretty good. A little bigger than what I wanted but I still used it.

MDPQT Final Thoughts

"Just my thoughts."

At this point I'm Trying to wash pebbles. I purchased to put into a dry river rock. I envisioned the bag being bigger since I ordered a 50lbs. I decided on this particular brand of gravel because of Amazon's add-on program. So far, really happy with how it looks in my small tank. The little package of clarifier included is not nearly enough. Snails and fish dont seem to mind the switch from sand.

"The color is beautiful."

I half rinse it and put it in my tank. Arrived in 8 sealed plastic bags inside one Priority box. I'd recommend but just be wary of debris. Using these stones for growing bulbs for church project. Purchased 9 bags of this for a new 180 gallon aquarium. Just be patient and realize that it's going to take a while to rinse it. The gravel adds amazing color and the fish and snails seem to like it.

"I split the 15."

It will take you a while to properly clean. The color mixture with the darker colors in it does that very well. Water became with film like on top and lots of little bubbles on every surface. But the gravel itself is nice quality and adds interest to tanks. Colors are exactly as shown on the screen- at least on my monitor. I wash it in small batches in a five gallon bucket before putting it in the tank. I've been using that for a few months now with my betta.

I WOULD recommend buying this item! I've been using that for a few months now with my betta. Everyone ask where did i get that color. Some of the bad feedback says it clouds the water. All substraight needs to be thoroughly rinsed before use. All n all, very happy with the purchase. Not sure why there is so much bad feedback for this.

Pure Water Pebbles 70152 First Impressions

"Great product."

I wash it in small batches in a five gallon bucket before putting it in the tank. Really just rinsed a little and ready to go. Just make sure you rinse it out REALLY good, before adding to your aquarium. Only issue is that it did have a hole in the bag but nothing too horrible. It smells like chlorine and epoxy glue. I did rinse it off before putting it in the aquarium. This was because of my own preconceived notions and not that of the sellers though.

"A few minutes."

Really just rinsed a little and ready to go. The color looks beautiful and natural in the tank. Unlike most, I didn't purchase this gravel for its ability to glow. Colors are exactly as shown on the screen- at least on my monitor. One bag was open and had emptied into the box. I used this for a small aquarium with 2 goldfish and it worked great! I wanted white rocks that were vibrant.
