About the company

The original company was started back in 1972 as CongaRoc Inc. Their product line was developed for the
Aquarium industry where they were the first to use acrylic resin to coat the product so that the raw material
is encased in an armor coating that protects your fish and plants, making the product pH neutral. It is also a colorfast,
non-toxic and environmentally safe product. It resists bacterial growth and staining, making it a superior media.
We still use that same process today.

Z2 Manufacturing LLC purchased the company in 2012 and saw a way to expand the line of products.
Today it includes Aquarium Gravel, Garden Rock, Garden Sand,
Houseplants, Terrarium and Fairy Garden Rock and Arts & Crafts Sand.
