Overview
• A blend of high-purity
aragonite particulate grades to simulate the natural substrate particle
profile of tropical reef lagoons.
•
Multiple particulate grades encourage biochemical reactions (e.g.
nitrification and denitrification) within the sediment to facilitate
continuous release of constituent ions (calcium, carbonate, strontium,
magnesium, potassium, and sixty minor and trace elements), encouraging the
growth of reef-building organisms and helping stabilize pH.
•
Over 39% calcium and 57% carbonate by dry weight.
• Applications include refugia, sea grass and macroalgae bed systems,
mangrove systems, and other methods of filtration employing substrate to
facilitate natural reduction of organic and nitrogenous waste, and reef
aquaria of all sizes (notably nano-reef systems).
•
Formulated by a marine
scientist.

Technical Background
Coral reefs may generally
classified as Atolls or as Barrier and/or Fringing Reefs; in a
sense, an atoll may be thought of as a barrier reef in the later
stages of development, for it is the subsidence of the land mass
around which fringing and barrier reefs form that leads to the
open water inside an atoll. As the interior landmass sinks into
the sea floor, an expanding area of water forms inside the reef,
called a Lagoon. These areas are largely protected from wave and
tidal energy by the ever-growing reef, and become a zone in
which particulates settle out of the water column and
relatively-delicate forms of marine life can exist and
reproduce. Organisms found in lagoons are primarily seagrasses,
macroalgae, disc anemones, colonial polyps, a wide variety of
soft corals and large-polyp stony corals, and detritivores
(filter- and deposit-feeding detritus consumers). Regardless,
the lagoon is where the majority of sand is deposited, with
particulate grading occurring throughout the depth of the
substrate. Similarly, the lagoon is a deposit for particulate
organic material, the re-mineralization of which (by microbes
and detritivores) corresponds with the observed rapid growth of
the organisms that have evolved to thrive in this habitat, and
resulting in the depletion of nutrients from the overlying water
column. Reef aquaria can benefit tremendously from the
employment of just such a system, with lower observed amounts of
particulate and dissolved organic material in the system being
an end-result. By creating the proper environment in a vessel
outside the main aquarium, a hobbyist can employ a sand bed of
the proper composition to house the bacteria responsible for
initial decomposition of organic material, and seagrasses and/or
macroalgae to remove the resultant substances from the system
altogether; the end result is often much-improved water quality.
Such a vessel may also be used to house invertebrates commonly
found in lagoons, creating a microcosm to observe and enjoy.
Brightwell Aquatics KoraLagoon Substrāt is a blend of several
grades of aragonite particles created specifically for the
purpose of emulating a lagoon environment. It is ideally-suited
to this purpose. |
