8.Cautions


1, due to the volume of volcanic rock crushing and transport, due to friction impact generating section residues and other debris mixed with the powder directly into the cylinder will cause cloudy water, use the water to soak for 24 hours, then after a few ADS wash the stone wells and other mineral residues, as well as the chemical composition of the packaging process purifiers other, you can put the cylinder in use.


2, has a softening effect alkaline PH value overall acidic volcanic rock under normal circumstances. But it does not exclude special water filter stone and other basic conditions to produce an initial placement test cylinder PH value check back often to avoid the special circumstances of the fish seedling damage. In general the impact of volcanic rock on the water PH value is between 0.3-0.5.


3, the use of 3-6 months, since the consumption of minerals in the volcanic rock, the proposed replacement of the lava. You can also use lava saturated brine will be used after 30 hours of soaking, and then water washing can continue to use the full ADS impurities. This is called lava reconstruction process. (Saturated brine refers constantly add salt to the water, salt melts, add salt until mixed solution of water and salt until the time no longer melt.)



Lava, stone and ammonia absorbing zeolites as non-toxic odor of natural non-metallic mineral filter material can be freely used in combination with, or placed against the use of specialized species, have gradually spread in ornamental aquaria. At this stage, the main players in the volcanic rock is aquarium culture and denitrifying bacteria filter for the fish to create a natural and enriched environment, landscaping and other aspects of use. As it can be laid directly on the sand bottom Bottom or replace it in the filter circulation system to use. Use the number depending on the type of fish, how many number of fish, other filter materials ratio, the size of the tank and other issues a decision. We can not be too superstitious and rely on some filter materials, should use a variety of combinations.
