Rowith 9-15mm 6kg

Rowith is a natural material. It consists of 99.1% calcium carbonate (CACO3) and is extracted from Jurassic and Devonian deposits.

Regardless of whether it is a substrate or a curing material for calcium reactor from Rodish, as opposed to broken corals, an additional entry of undesirable substances (eg phosphates) to the aquarium avoids.
