This stuff is excellent for salt water fish tanks. All you need to do with this sand is add the sand then add the fish. It is as easy as that. This sand comes with several different benefits including an enhanced buffering capacity, maintaining proper pH levels, instant cycling, the removal of harmful nitrates, and the removal of ammonia and nitrite.Here below is a list of companies/websites that sell sand for fish tanks. If any of these links doesn't work any more, let us know via the form that is at the bottom of this page, please.Another positive aspect of sand is that it’s far gentler on fish that search in the substrate for food. Fish like are constantly sifting through their tank’s substrate in search of food and their sensitive barbels can be easily injured. Sand more closely resembles their natural habitat, and they can sift through it without threat of injury.One last thing to consider is "where" the medium comes from. Sand (like the type used in a children's play sand-box), gravel (such as the kind found in fish stores that comes in pretty colors that is primarily sold for freshwater tanks), as well as rocks that are quarried on land often contain unwanted minerals, metals, silicates, and possibly chemicals or toxins that may leach out into the aquarium water and become problematic.With gravel or sand, you will have to decide how much to get. The recommendation is 2 inches of gravel for tanks up to 55 gallons, and 3 to 4 inches for larger aquariums. With sand, you want to have 1 inch of sand for tanks with small burrowing fish and 2 inches for larger burrowing fish. A good guideline for most tanks is to purchase 1.5 pounds of substrate per gallon. However, this guideline is inaccurate for tall or unusually shaped aquariums. Resort to trial and error if necessarily.Also, do some research to decide what fish will thrive with a sand substrate and which won't do as good.
Sand can be used in salt and some freshwater tanks. Don't use sand with Goldfish, for example, because they will just grab mouthfuls of it when looking for food, and obviously, that's not good for them.
