Red Sea offers ideal substrates for all marine fish & invertebrate aquariums, Testing has shown that using these substrates will maintain a stable pH and a high buffer capacity over extended periods of time. Furthermore the porosity of the spheres provides an excellent media for both aerobic (nitrifying) and anaerobic (denitrifying) biological filtration.

 
Reef Base consists of naturally occurring reef sand spheres mixed with aragonite coral chip. The spheres are highly porous calcareous shells of simple protozoa (foraminifers) and bring many benefits to all marine aquariums. Reef Base substrate contains natural aragonite (the most dissolvable from of calcium carbonate) that maintains natural levels of pH with its high buffering capacity. Furthermore the porosity of the spheres provides an excellent media for both aerobic (nitrifying) and anaerobic (denitrifying) biological filtration. Each bag of pre-washed, impurity-free Reef Base will provide the right quantity of substrate for a 2”(5cm) layer in a 10-gallon(40 liter) aquarium. This is an ideal substrate for all fish and invertebrate tanks.
