    • Clean, dark, and easy to work with

Compared to other aquarium sands I’ve used, this one stands out for how clean it arrives and how even the grain size is. The black color is deep and looks excellent once submerged. Minimal rinsing needed and no sharp edges, which is important for fish. It was easy to shape for aquascaping and stays put once placed. For the price, this is a great value and performs better than many similar substrates. ... show more

    • Very Good Sand, No Sparkle
Style: Pet Supplies
The media could not be loaded. This is great sand. When I put it in the tank I did not have murky water like I did when I put white sand in. I gave both white and black rinsing before I put it in. With the black sand however I added more once the tank was full and I still didn't have a problem. Now I have a lot of Corys that like to kick up the sand during their Cory parties, but it never affects the water clarity. Honestly I was excited to see the "Galaxy" sparkle, but the only way I see it is in my video. In real life I do not see it. My video was taken with blue light so that's why it might have shown up. Again, in real life it doesn't. It's still good sand and I'm glad I got it. Just don't expect a meteor shower in your tank and it won't be a disappointment. The price was reasonable and delivery was very fast, but then again it was Amazon so I expected that. I hope this helps some of my fellow fish keepers! ... show more

    • Plants grow well in it, it looks great, and is acceptably clean
Style: Pet Supplies
This is my favorite substrate, and I've used it on probably 6-7 tanks over the years. It does have a little cloudiness, but it clears up within a day or two and isn't bad enough to be harmful to the fish. I've NEVER done an at-home rinse any of the times i've used this stuff, and it's always been perfectly usable straight out of the bad. Has a nice little sparkle under good lighting, and looks great in general. Very small grains, similar in size to those of the "white sugar sand" from the same brand. I like to pair this with their black gravel. Plants grow perfecftly fine in it, and i've had success with all of the standard fish tank plants (java vern, amazon sword, dwarf grass, etc) Overall, i've always been pleased with this substrate and will continue to use it. ... show more

    • I really like it
Style: Pet Supplies
I really like this stuff it’s the best looking sand on the market in my opinion. It’s not sharp. It doesn’t change water parameters

    • Very dusty

Good product, just very dirty. Allow several days of tank filtration before adding fish.

    • Changed from that small gravel to this sand! Much better
Style: Pet Supplies
We have many tanks, a 125 gal is our biggest. We switched from that colorful rock to this sand and we loved it and changed all the other tanks to. The appearance is much butter. Stays cleaner to. The gravel was holding to much yuk. Great quality true to color . A great value. Good size bags

Review Image by Rebekah
This is a picture from today. I bought this back in August of 2024, and it's still holding up great! After the first few initial rinses (as you're supposed to do), the water has never been cloudy. The color of the sand still looks new. It does not clog up the filter. It's safe to use with aquatic turtles. My only complaint is that it leaves some black substance on a few surfaces, such as the leftmost artificial plant in the photo. If you use more non-porous decoration, you'll be fine. ... show more

Rinsed this by putting in a bucket and running the water until it was clear. This happened very quickly. It's very satisfying to work with underwater and looks fantastic.
