"I recommend!"

It worked really well and still allowed new stems to pop through. The glow is pretty minimal but it still looks nice. I baught a 5 gallon tank and i had to buy 2 packs. The color of the gravel makes the blue in my Tetra's and Gourami's pop. I decided on this particular brand of gravel because of Amazon's add-on program. This is not the colored synthetic aquarium medium. Color is good contrast to the Beta.

"Nicely polished."

I used these to put on top of soil if my pot plants. There's a nice mix of color and gives my little nano tanks a nice earthy feel. Removed pebbles and refilled for the 3rd time. I used this for a path in a 22 gallon aquarium. The rock arrived quickly and several days before projected. I rinsed it about 3-4 times and felt satisfied it was good. Overall I am very pleased with my purchase and would suggest this product to others.

"I recommend!"

Just be patient and realize that it's going to take a while to rinse it. I did rinse it off before putting it in the aquarium. But the gravel itself is nice quality and adds interest to tanks. I have a 90 gallon aquarium with a footprint of 18 by 48 inches. There's a nice mix of color and gives my little nano tanks a nice earthy feel. Not sure why there is so much bad feedback for this. I wished I would have bought a few more so It would be deeper in my tank.

"I really like the stones."

So far, really happy with how it looks in my small tank. For reference, my tank is a 20 gallon tall tank. So if you are looking for bigger size, this is not it. I purchased to put into a dry river rock. I am disappointed that there seems to be nothing special about this gravel. Works great in my daughter aquarium. Colors are exactly as shown on the screen- at least on my monitor.

"Didn't take long to wash."

I have a 90 gallon aquarium with a footprint of 18 by 48 inches. Unlike most, I didn't purchase this gravel for its ability to glow. All n all, very happy with the purchase. I do not own glofish nor a glofish tank. It's my new, absolute favorite substrate. The texture is smooth so cories and burrowing fish will not hurt themselves. The glow is pretty minimal but it still looks nice.

SACKORANGE Final Thoughts

"I haven't used this yet."

I'd recommend but just be wary of debris. I actually used this on the top of my potted plants to keep gnats away. I'll definitely use this gravel again the next time I start a new tank. For reference, my tank is a 20 gallon tall tank. It smells like chlorine and epoxy glue. Not sure why there is so much bad feedback for this. The little package of clarifier included is not nearly enough.

"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.

"It's gravel."

I didn't even need the water clarifier, and I found it in the bag. I recommend doing it in smaller portions. I've ordered their midnight pearl color and it is beautiful too. I've been using it now for a couple of months and nothing has happened to them. The pebbles are a perfect size for 30+ gallon tanks. I'm accenting with multicolored glass rocks to accent. My Vallisneria and amazon swords grow just fine in this substrate.

Very random shapes and colors that blend well. Don't use any soaps or anything else. I am disappointed that there seems to be nothing special about this gravel.

"It is quite lovely."

This gravel works extremely well for planted tanks and for smaller fish species. Overall I am very pleased with my purchase and would suggest this product to others. The pebbles are a perfect size for 30+ gallon tanks. I was scared to buy it after the reviews I read about it killing their fish. Just do a proper rinse, and you will be fine. These colors combine to give an overall color of light brown. Don't own a blacklight so can't tell if it glows or not.

"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.

"Wet vs dry."

Minimal clouding gone within 12 hours. I use a hybrid of the Walstad Method, and this stuff is perfect. Using these stones for growing bulbs for church project. There is some sand and dirt mixed in. Had to move fish out after it nearly died. All substraight needs to be thoroughly rinsed before use. Don't even waste your time adding it to your tank.

I have a 90 gallon aquarium with a footprint of 18 by 48 inches. Just do a proper rinse, and you will be fine. One bag was open and had emptied into the box. I filled with filter water ad let sit for a day before relocate fish. It looks great and didn't change anything about the water. Really just rinsed a little and ready to go. It really makes the tank look sharp and I believe the goldfish likes it, too.

It comes in a variety of colors, but I prefer the classic white. Worked great for my succulent gardens. Needs more plants but it makes the colors of the fish and other decor really pop.
