CaribSea Aragamax Oolitic Select Sand 30 lb
Aragamax Oolitic Select Sand:0.5-1.02 mm grain size. This product is a Breakthrough! This uniformly graded oolitic aragonite not only provides nitrate reduction in shallower aquarium beds, but also has an increase in pore water space which allows maximum diffusion rates of minerals and trace elements. The only oolite product suitable for plenum filtration systems.
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.
