In fact, many hobbyists do–this has certainly been one of the top-selling substrates in the industry for quite a few years now! If you prefer a light colored substrate, but prefer some colorful highlights (rather than pure white), then you’ll likely find this product to be extremely appealing. Its pale rosey hue makes it blend a bit more with coralline-encrusted live rock. The overall effect, at least from a bit of distance, is a nice soft pink color. It’s more like… a blend of mostly beige with flecks of reddish and pinkish material. Fiji Pinkĭon’t be expecting a solid, bright pink with this one. As such, it’s a great choice for a low flow (e.g. This sand is of a fine grade and high density at 0.25-1.0 mm diameter and 96 pounds per cubic foot. Moreover, it easily passes through the gills of sand-sifting fishes. high surface area) and low interstitial flow rates promote the growth of beneficial anaerobic bacteria. Bahamas Oolite is excellent for use in deep sand beds (DSBs) where its extremely small grain size (i.e.
Formation starts with a small fragment of sediment acting as a “seed” such as a miniscule shell fragment. Unlike all of the other substrates here listed, which are formed from the erosion of larger bits of rubble, oolitic sand is formed from the precipitation of calcareous materials in warm, shallow, highly agitated marine intertidal environments.
Independent lab tests prove that ARAG-ALIVE!™ technology allows for faster cycling than with other substrates, including other live substrates. These microbes “come alive” and contribute to aquarium cycling as soon as the sand is emptied into the tank and biologically activated. All of these examples are extremely popular offerings from their ARAG-ALIVE!™ product line, namely Bahamas Oolite, Fiji Pink, Special Grade Reef and Hawaiian Black.Īs “live” substrates, the ARAG-ALIVE!™ products are packaged slightly wet and are coated with live spore-forming bacteria. The following are branded materials distributed by the old-school aquarium substrate giant CaribSea (Fort Pierce, Florida). We here take a look at some marine aquarium substrates. While different aquarists have different budgets and goals, and may be attempting to recreate very different biotopes, there are a few substrates that are overall great in terms of appearance as well as function. And, even more importantly, you might find that it has a substantial impact on both the short-term and long-term health of your system.

But in the end, when you’re snapping those full tank shots for Facebook, you might be surprised how much the color and even grade of your substrate can affect the look of your display. Maybe some of us quite frankly don’t put much thought into it at all. Sure, maybe substrates are the last thing we dream about when we’re planning our next big tank build.
