Usually one application is enough to reduce the nitrate
level to zero and maintain it at that level for a number of weeks
or months. Many customers make one application and then are free
from blanketweed for more than one year. Others require more than
one application. The pondkeeper is advised to check nitrate levels
on a regular basis, say, once or twice per week to see how the Viresco™ is reducing nitrate. Many people see nitrate moving to zero in less
than a week: for others it takes a few weeks to reach zero. We suggest
that, if little perceptible change is observed within, say, three
weeks, another dose or part dose should be used. We would suggest
that the pondkeeper considers the application of maintenance doses.
However, we do not wish to recommend specific amounts at specific
times. Our microbes do lose some of their viability over time as
each generation of new ones succeeds the previous.
It is therefore worthwhile using a nitrate test as an indicator
of when more product might need to be applied.
However, every pond is different and each pondkeeper
will do things differently. One customer decided to double dose
with Viresco™ Koi to begin with and then to put in half a dose every two weeks.
This turns out to be a successful method for him.
Application Procedures
It is recommended that the Viresco™ products
are dissolved in a small amount of pondwater, left for a few hours
and then bulked up with more pondwater before being added direct
to the water in different places around the pond. Ideally the powder
should be mixed in the morning, left with an airstone and introduced
into the pond in the evening. Intermittent use
of an egg whisk can be made if an airstone is not available.
It is important to keep the solution in a shaded
place indoors. This is because the UV radiation from daylight could
damage some of the bacteria in our products.
Water Temperatures
We state that our Viresco™ microbial based products work best in water with temperatures above 50°F or 10°C. However, there is an advantage in having the Viresco™ microbes in the water at temperatures lower than this. When fish are coming out of their cold-spell in late winter or early spring and start feeding again, their immune system is at its lowest. This is when they are liable to pick up a fungal or bacterial disease. Having the Viresco™ microbes in the water at that time, will tend to suppress any micro-organisms present in the water that might otherwise form a disease.
Above 10°C, the optimum working temperature for our microbes is between 30° to 33°C. Temperatures above about 37° will kill the microbes.
