1.0–2.0 mm diameter grain size. A revolution in reef-keeping! This is the one you’ve been reading about in all the hobbyist publications. This grade of aragonite is specifically engineered for plenum-type nitrate reducing beds or anywhere a deeper bed is called for. The pore water space created by precision grading also allows maximum pH support and dissolution of calcium carbonate.

CaribSea Aragonite buffers to the highest pH and delivers more calcium, carbonate, and trace elements than any other substrate. Little or no rinsing required, aragonite keeps aquariums healthier, longer.

This sand may be a little too rough to use with sharks. I would reccomend something with a smaller grain size.

Self levels in aquarium well, Great size of substrate, Does not blow around with water flow,

Needs a LOT of rinsing, but once rinsed works great.
REVIEW
In my previous aquariums I have used a wide variety of substrate. I purchased 80lbs for my new 75 gallon aquarium.

The dry aragonite special grade is a great size and color. It does not blow around like lots of sands or smaller sizes and very easy to work with.

I do recommend THORO...Read More
