CO2 Aquascaping

Aquascaping plants need light energy and carbon dioxide (CO2) to synthesize the sugars that provide them with energy. In this category, you will find all the necessary equipment for injecting carbon dioxide into your aquarium and controlling it via pH.

Info: for a pH below 6, nitrogen, calcium, magnesium, molybdenum, phosphorus, potassium, and sulfur are difficult to absorb. Additionally, some metal oxides such as aluminum, copper, iron, and manganese become so soluble that they reach toxicity levels.

When the pH becomes higher than 7, there are blockages due to excess calcium on various elements, especially iron, but also boron and manganese, which become insoluble, with phosphorus crystallizing as non-assimilable tricalcium phosphate. Another well-known interaction is that of potassium, which displaces magnesium and calcium from the clay-humus complex. This is the famous decalcifying action of potassium fertilizers, where some absorbed ions reduce the assimilation of other ions. This is known as ionic competition.
