CaribSea Seaflor Super Reef
Seaflor Super Grade Reef Sandô is a mixed-grade aragonite substrate that is perfectly suited as a reef tank bottom cover or for use with nitrate-reducing systems. The addition of small shells makes it ideal for aquariums with mature jawfish or burrowing invertebrates. This substrate will naturally maintain higher pH (8.2+) and provides maximum surface area for water purifying bacteria.
Grain Size: 0.5 to 2 mm
