Aqua Natural Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 1-2mm

Love this sand. I did wash it additional times and the water still looked a little cloudy

Arrived on time as expected.Looks nice and is shiny in my tank.

excellent

Absolutely beautiful. I rinsed the sand in a bucket with my hose until most of the micro particles were rinsed out. It glitters under the light and did not impact the water quality or color. I gave it 4 stars because about a half cup of sand had spilled in the shipping box.

Nice semi sparkly black substrate

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!

Little pricey for the amount of gravel you get.

Great product! Looks amazing in my tank!Highly recommend for a beautiful black sand look! Like any substrate it takes about 24hrs to settle and water to clear. Nothing out of the ordinary!
