When you compare large ponds, small ponds, and aquariums a general rule of thumb is that the smaller the system, the more difficult it is to maintain balance. This rule is well known to aquarium hobbyists. In a ‘natural aquatic system, various microorganisms work together to remove excess nutrients and maintain a balance in water-quality parameters. However, aquariums are almost always overstocked with fish, plants, or other organisms to a point that these microorganisms [free-floating and attached to surfaces] can no longer keep up with the load. To compensate, biological filters are added to handle the load of incoming nutrients. These filters add more surface area and rely on various microorganisms to capture excess nutrients and remove them from the system. But even these filters are subject to overload or environmental parameters that disturb their delicate balance.
The simple solution for an aquarium that is experiencing water-quality issues is most often to significantly reduce the number of fish. This is usually an undesirable solution for most aquarists. So, the other option is to increase the efficiency of the current system’s nutrient handling biota. This is where BZT® Aqua 4-U fits in. BZT® Aqua 4-U contains a blend of microorganisms and enzymes, formulated specifically to help maintain water-quality and biofilter performance. Solids are broken down and eliminated while nitrogen compounds like ammonia, nitrite, and nitrate are reduced or eliminated.
All this means a more-aesthetically pleasing aquarium and a healthier environment for the fish, plants, and other organisms that live there.
