Description

Quartz Gravel is the Rolls-Royce of our range. Natural Quartz not only looks wonderful but has also been shown to help reduce the build up in the aquarium. This is partly due to the huge surface area of quartz which offers added space for the establishment of tank cleaning bacteria. Quartz sparkles underwater due to the many light reflecting facets and is a striking substrate that contrasts well with aquarium plants such as anubias and amazon swords.

    • Very very fine - almost like sand - beautiful!

I ordered this to add a “sediment” layer for my aquatic plants, and to give a different landscape for my betta Tatsu. I rinsed and soaked them in a bucket overnight to get all the debris out and peace of mind that it’s clean; definitely helped with the cloudiness prior to adding. I added a thin layer across the pea gravel I already have; it was plenty of material for my 10 gallon tank. If used alone with no other substrate/rocks, you’d probably need 2 bags of this for a 10 gal. My pet peeves but doesn’t totally kill the vibe: 1. They don’t sparkle under water at all ☹️ 2. If you have a foam filter like mine that sits at the bottom, these quart rocks are as small as sand and my filter sucked them up and clogged it. I will be getting a top flow filter instead, so not too annoying. 3. I will update once I do a complete tank clean to share how difficult it is to clean with how small they are - by the looks of it, it’ll be a challenge. Wish they were larger size! ... show more

    • Very attractive substrate
Size: 10LB
Not what I expected, but works really well in my Betta aquarium. It has very attractive sparkly grains in it. It also works well as a substrate for plants, everything I planted is thriving.

I've used 4 bags in my 40 gallon tank. 2 bags wasnt enough for all the micro bacteria. I love being able to make a realistic surface with it (no flat). My live plants have died, I haven't tried cleaning yet, but I got a siphon specific to sand. This is very close to sand.

    • Sparkles when dry, not too dirty, does have some lighter rocks in it, but is pretty good regardless
Size: 10LB
To address other reviews: It does sparkle, but primarily when dry. It does say it is quartz gravel. However, when wet/underwater, it doesn't really sparkle much. It's not that dirty of gravel. If you ever buy natural gravel from any brand, it's always dirty and needs lots of rinsing, even when prewashed. Just being moved around, the gravel will grind away on itself and create dust. I'd say that I didn't have to wash this gravel nearly as much as the super cheap stuff at Petco, but i still rinsed about 3-4 times to get it to stop clouding water. It's also kind of in a space between gravel and course sand. It's one of those situations where we have to start debating the semantics of sand vs gravel before we can really call it one or the other. It's very fine gravel, or very course sand. It's mostly a bit smaller than the listing says, as i don't think that many of the pieces are actually around 2mm. There are some lighter-colored pieces in the mix. There aren't a ton of them, but enough that I could see fish confusing them for food or something. However, I doubt it's as big of a problem as people make it out to be. I personally like the black gravel with a small amount of lighter bits, as it makes it feel more natural and gives it more of a visual "texture". I can understand being disappointed if you want all jet-black gravel, but honestly I've never seen any gravel that was entirely black without it being artificially colored. I like this gravel because it's a good size for my pea puffer. It's not as problematic to work with as normal, finer sands, as very few pieces in the mix will float in the water column, even when being stirred/cleaned in a big bucket full of water. I find it attractive and easy to clean. My actual only complaint about it is that it's very pricey compared to many regular sands or gravels. ... show more

    • Beautiful Black Sand
Size: 10LB
Review Image by janelle janelle
The media could not be loaded. Just set this up tonight in about an hour of time. Was sketch about getting the black sand and reading the reviews. However, if you do as everyone says and clean it, and then when you think the waters clean then rinse it one more time. I did this about 8 rinses in a kitty litter bucket we only use for freshwater. This picture is 5 minutes after I added the last bucket of water. Key point is to use a bowl and set it in the bottom and let it float around as you pour the water in, hitting the bowl with the water every drop. Crystal clean and looks amazing. Highly recommend this product if you do the right steps! Ps as you can see in the video it is not entirely black, but I love the color contrast and how it glistens off the LED light. ... show more

    • My favorite!
Size: 10LB
Love how fine and soft this is for my pleco to lay in and sift through and it doesn’t affect my water perimeters at all like rocks do. I would highly recommend washing multiple times and draining all the dust shavings before adding and then allowing it to settle in the tank before adding your fish. Only con for me is It is hard to clean without a tank vacuum ... show more

    • Beautiful coarse sand
Size: 10LB
This is not fine sand nor is it small gravel. It's large sand. It is pretty easy to work with unlike sand and is easy on the bottom dwellers unlike gravel. Naturally colored it will bleed out a little while preparing. I did several rinses and soaks over 2 days before putting in the tank. It sparkles under the light but with no glare. vacuums pretty easily, you will get some up the tube but just let it sink to the bottom of the bucket, pour out and pinch it back into the tank. Simples. Would re-order again. This is the only thing IMO that competes with Carib Sea Supernaturals Peace River which is the perfect substrate in all situations. Just hard to fine and boring in color. ... show more
