Applications
Markets specifying this grade
Aquarium and aquaculture
Provides a carbonate substrate that supports alkalinity in systems drawing it down, and a grain size matched to livestock and flow.
Water treatment
Dissolves into low-alkalinity water passing through it, raising hardness and buffering capacity.
Aquarium selection
Selecting for an aquarium
Aquarium applications for this grade, and where another grade is specified instead.
Cichlid and hard-water systems
Particle size suited to systems where the substrate is worked by livestock and where an open bed is wanted.
High flow and contact media
Highest flow resistance of the three. In a vessel or sump the larger particle maintains flow through the media rather than around it.
Not for a level sand bed
Reads as gravel rather than sand, and detritus passes into the bed rather than resting on it. Specify fine or medium.
