"...with the KORALLIN Kalkreaktor, I'm finding my pH remains slightly higher as no excess CO2 is entering my aquarium, there is no heat or noise associated with the Eheim pump, and energy consumption is extremely low. Add to that its extremely small footprint and it makes for a unit that is probably impossible to beat in features and price"
