way to lay coral sand or volcanic stone at the bottom of the arhat fish tank? First of all, coral sand can stabilize the water quality and keep the water weak alkaline for a long time. It is also better to use coral sand on the filter, because their filtration is stronger. Volcanic stones can also
be placed, which can adsorb harmful substances and heavy metals in water, and then release trace elements. These trace elements can promote the metabolism of Luohan fish and help them discharge harmful substances from their bodies. Moreover, the volcanic stones are red, and laying a layer of volcanic stones can promote the color of Luohan fish.
Luohan fish? Luohan fish likes weak alkaline water, and the PH value should be controlled between 6.5 and 7.2. They have high requirements for water quality, so breeders need to change water 2-3 times a week, and the amount of water changed each time should not be too much, which should be controlled at one third of the total amount of water. If conditions permit, a circulating filtration system can be installed to ensure clean water quality. When feeding at ordinary times, we should also pay attention to the amount of feeding not too much, so as to avoid food residues polluting the water quality. Food residues need to be fished out after feeding every day. If conditions permit, coarse salt can be added every time the water is changed to sterilize and disinfect.
