For good condition
A natural starting aid for the pond. The growth substrate for oxygenating plants ensures that the pond water and oxygen plants remain in good condition. In other words, free from algae and with enough CO2. The nitriﬁcation process can be initiated because of its porous structure. This is essential for supplying oxygen plants with nutrients and carbon dioxide (CO2). And these, in turn, are needed to stimulate vigorous growth and the creation of oxygen.
