Aquarium Sand & Gravel Substrate for Saltwater & Freshwater Tanks

In the ocean, the sand bed is home to an amazing diversity of living things. In a mature saltwater aquarium, lots of things live on, around and in the sand bed, too. Microscopic bacteria and tiny invertebrates call the sand home and have an important role in keeping your aquarium system balanced.

Sand, in a saltwater aquarium, can provide one or more of the following functions:

Biological filtration, in a saltwater aquarium, is performed by bacteria that grow on the live rock and on the live sand in your aquarium. Aquarium sand is a substrate with a lot of surface area and creates a perfect home for those biologically beneficial bacteria to grow on. But that doesn’t mean that you have to have a sand bed to have a good biological filter. Plenty of aquarists are successful keeping reef tanks with absolutely no sand bed at all. These tanks are often referred to as bare bottom tanks. But plenty of life will inhabit your sand bed if given the chance.

Brief review of Nature's Ocean Bio-Active Live Sand For Saltwater Tanks And Reef Aquariums. By NewYorkSteelo.Facebook Fan Page: This is my first saltwater aquarium. I just bought it off someone on craigslist today. So far all I have is the sand, water, and filter. I don't have salt in there yet, but I have the filter going to help with the cloudiness in the meantime. The sand is PLAY SAND!! I know a lot of people would highly advise against using it, but I've done a lot of research and hopefully it'll be ok. The water's not filled all of the way yet because I haven't added the salt. Oh, and I'm also using tap water... we'll see what happens. The nerve, I know..

The first step after removing living creatures from the saltwater tank is to disconnect the filter, lights and other accessories. Drain the tank of all saltwater and discard the filter pads and sand. You can't reuse sand from a saltwater tank in a freshwater aquarium. Give away artificial plants and accessories that you can't sterilize wholly, those that are hard to clean. Set aside any accessories you want to keep.

Film Shot on Sony Xperia Z5It turns out that aragonite sand initially DE-BUFFERS —and once it stabilizes in your saltwater aquarium, it isn’t going to do much of anything at all unless your pH drops crazy low—as in below the of neutral freshwater. So…eh…I humbly apologize for not know that. It kind of blows my mind. I’m positive I’ve read the OPPOSITE of that in a bunch of places. The buffering capacity of the sand is often touted as a benefit for keeping the pH of your aquarium stable.
First, drain some of the saltwater in your aquarium to allow for the sand you're about to add and turn off the power to the tank. We'll use the 5-gallon bucket to clean the sand. Use the 5-gallon bucket to pre-mix about 2 gallons of saltwater. Add your sand to the bucket and then stir. This will allow some of the dust and dirt to rise so you can then siphon it off. Drain some of the saltwater from the bucket before adding your substrate. Use a plastic cup, ladle or something similar to add the freshly cleaned substrate to your aquarium. Use one of your power heads to blow off any sand that gets on your live rock during this process.
