Your cart is empty.Included in this pack is 1 x 5lb Bio Substrate - activated bacteria seeded substrate, and 1 x 10lb dry aquarium substrate. Diamond Black 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 looks like diamonds have been added to your tank. Adding the Bio Substrate to the dry substrate will create an instantly cycled aquarium, it contains a patented blend of live nitrosomas and nitrobacter bacteria which break down and convert harmful ammonia into nitrates.

This is a good gravel, very fine but not sand. Very dark black that contrasts neon colors, easy to use not too dusty on setup

very nice substrate, easy to clean and looks great. however, even though its prewashed and screened, do your self a favor and rinse the substrate out anyway before adding and cycling your tank. there was small debris in it and the rinsing water came out visibly brown tinged for 2 rinses. not a deal breaker as it is very nice substrate, and 2 rinses was all i needed to do which is much better than other substrate

I usually use Carib Sea Pesce Ricer gravel. Bought this bcuz it was to deliver sooner. Decent substrate. Added benefit of a 5# "pre-seeded" bag of substrate. Although I didn't need that since I just use media from my existing established aquariums to establish new tanks. But someon3 who was starting a new tank could benefit from this 5# bag. I like to color. Almost clear after 12hrs running filter. Didn't rinse. Wasn't terribly cloudy at first, but did cloud the water up.

It is beautiful and easy to use. My fish love sifting through it.In my opinion it is worth the price.I have it in a 60 gal breeder and a 36 bow front.It is spectacular for Cory's and other botton feeders as well as goldfish.

I'm thoroughly impressed with Aqua Natural’s Bio and Dry Substrate! It looks beautiful in my aquarium, is easy to set up, and promotes excellent water clarity. My plants are thriving, and my fish seem happier than ever. The substrate provides a stable environment, supports beneficial bacteria growth, and maintains water parameters effectively. Definitely a top-quality product—perfect for anyone serious about creating a healthy, attractive aquarium environment.

I changed out the old blue unnatural gravel in my betta tanks to this new gravel. My tanks look much better now and much more natural. I used both the dry gravel and the bio gravel packs, about half of each bag for each tank and it was just enough for my two 5.5g tanks to have around a 1.5-2 inch layer. I also like that the grains of this gravel are smaller than those of my old blue gravel, and are mostly rounded and smooth.

This item is listed as two items. One bag of regular subtrate and one bag of bio subtrate. I only received one bag. My son is super disappointed that we have to send this back. Not paying $40 for one 10lb of gravel.
