When aerated and/or when there is strong water flow, a gas equilibrium between the ambient air and the water is established. This also results in a corresponding, but very low CO2 content in the water, which cannot be changed by aeration. HOWEVER, this low CO2 content is far too low for most aquarium plants to thrive. Therefore, aquarium owners must rely on additional CO2 supply through CO2 fertilization systems. The higher CO2 content achieved in this way is reduced by ventilation and strong currents or, as it is called in aquarium terminology, expelled. For this reason, well-planted aquariums should only be lightly ventilated at night if necessary.
At first, air hoses and special CO2 hoses are flexible and can be easily attached to the connection pieces. After a few months, the hoses harden more and more and can only be removed from the connection piece with considerable force. If you pull hard on the hose, this will damage the connection. In the worst case, it may break off. Therefore, cut the hoses to be removed at the side and remove them carefully. Always install the hoses with a little extra length.
JBL PROSCAPE SOIL varieties are small pellets made from fired clay. JBL PROSCAPE PLANT SOIL also contains added nutrients, which is why using it as a soil filter causes a strong flow through the soil and thus a strong leaching of nutrients from the soil. This provides a larger amount than the plants usually need, resulting in a surplus. The service life is greatly reduced. The bigger problem is the durability of the firing when used as a filter medium for the soil filter. The pellets are subject to greater wear and tear due to friction and flow. This constant abrasion creates a kind of sludge that rapidly reduces the filter performance. Classic soil types that allow sufficient water flow are suitable for this type of filtration.
