KoraLagoon Substrat

  • Brightwell Aquatics KoraLagoon Substrat is a blend of several grades of aragonite particles created specifically for the purpose of emulating a lagoon environment. Multiple particulate grades encourage biochemical reactions (e.g. nitrification & denitrification) within the sediment to facilitate continuous release of constituent ions (calcium, carbonate, strontium, magnesium, potassium). These encourage the growth of reef-building organisms & help stabilize pH levels. 


    Using Brightwell Aquatics KoraLagoon Substrat will also facilitate natural reduction of organic & nitrogenous waste. It is highly effective in nano-reef systems. It can also be placed in refugia, seagrass and mangrove systems & reef aquaria of all sizes.

  • If desired, briefly rinse substrate in purified water prior to placement in aquarium system to remove dust. KoraLagoon Substrat may be employed in a number of applications, however in each case it is recommended that the total depth of substrate not exceed 2.0 in. (5.1 cm). 


    To determine the approximate amount of KoraLagoon (lbs.) required for a given container (aquariums, refugium, etc.), multiply the result by 0.05.
