AZOO Calcium Reactor
1. Raises the carbonate (KH). Releases from many positive ions, and prevents water from acidification.
2. Can connect to any existing powerhead or external filter. Only requires a small amount of water to circulate the calcium.
3. The flow path design consists of double tiers of tubular material and vortex plate, that triples the flow path. It helps CO2 totally dissolve into the water.
