1. Basics
In fresh water aquaria, the pH-value decides on the percentage of free carbonic acid. The carbonic
acid fertilisation is the basis for a well thriving plant population. The pH-Computer maintains the
set pH-value automatically by the addition of carbon dioxide.
The pH-value and the regulating of carbonic acid is of special interest in sea water aquariums when
used in conjunction with a calcium reactor. The pH-Computer can be used to regulate the input of
carbonic acid.
2. Features
Aqua Medic computers are microprocessor controlled units. They are safe, reliable and meet all
requirements of professional measuring and regulating devices.
