Hardening granules for fresh and sea water
Special features:
- excellently suited as a hardening material for lime reactors
- Ideal for use as substrate in saltwater and harder freshwater aquariums
- Additional buffering (pH stability) of the aquarium water and supply of total and carbonate hardness (higher degrees of hardness can be achieved by adding CO 2. )
- ideal growth body for microorganisms (e.g. nitrifiers).
-
As a filter material in the biofilter, it buffers the acid produced by microorganisms very well.
- Available in 2 different grain sizes : 2 – 3 mm and 9 – 15 mm grain size
ROWA ® lith is a natural material. It consists of 99.1% calcium carbonate (CaCO 3 ) and is obtained from Jurassic and Devonian deposits.
Whether as substrate or hardening material for the lime reactor, ROWA ® lith avoids the additional entry of undesirable substances into the aquarium (e.g. phosphate), unlike when using broken coral.
We also use ROWA ® lith in drinking water treatment as a deacidifying agent.
