![Seachem Laboratories Presents Seachem Onyx Sand 7kg (15.4lb) Ph Stabilizing Planted Freshwater Aquarium 7 Kilo. Onyx Sand is a Specially Fracted, Stable Porous Gravel for the Natural Planted Aquarium. Being Carbonate Rich, Onyx Sand Provides an Advantage to any Plants Able to Utilize Bicarbonates. Although Ideally Suited to Planted Aquaria, it may be Used in any Aquarium Environment. Onyx Sand is Most Effective when Used Alone as an Integral Substrate Bed, but it may be Mixed with Other Gravels. Gravel Modifiers Such as Laterite are not Necessary. Onyx Sand is not Chemically Coated or Treated but does have a Slight Buffering Capacity that may Raise Ph by 0.1 - 0.5 Ph Units (Depending on Source Water Characteristics). Although Pre-Washed, it should be Rinsed Before Use to Remove Residual Dust. Dust can also be Minimized by Filling Tank Slowly and Dispersing Water so that the Onyx Sand Bed is not Disturbed. Slight Initial Cloudiness is Normal and will Clear Rapidly. 7 Kilo [30326]](http://cdn.petcarerx.com/img/PrdImg/408x408/20060_001_xl.jpg)
