Temperature
of pond water at testing is 73.4 -73.5 ºF
(23.06 ºC) Date: 08-10-13. Now that it has been
10-days after a water change of about 450-USgals out of 1250-USgals of pond water
and the prefilter was cleaned about 22-hours ago.
The
last time I showed pond water parameters it was before a water change (Hadn’t
done one in over 30-days.) and before and after a prefilter cleaning. TDS And Conductivity (EC) Test... and the Anoxic Filter vS Lake Michigan water. All test
were conducted with a Hanna HI 991300 TDS and conductivity-measuring device. The 500-ml beaker shows water taken
right from the Anoxic filters waterfall outlet and displays the turbidity of
the water. It is quite evident that the pond water is quite clear and NO3 is < 5-ppm as tested by
LaMotte water quality and analytical testing equipment test kit.
Also
I will add that a Bart Biodetector test was conducted, which is nothing more
than a biological activity reaction test done to test Heterotrophic Aerobic
Bacteria (HAB), Sulfate Reducing Bacteria (SRB) and Iron Related Bacteria
(IRB). These are the three most important agents involved in biofouling with
most conventional filtration systems. This same topic of discussion was on the web
forum Extreme Koi in the UK; why such test are important and if they are
really needed. However, what hobbyists don’t understand is that these Bart biodetector tests can tell if an abundance of these bad bacteria existed, then
they can cause corrosion, clogging, fouling of the pond water, and the increasing
hygiene risks to our animals if these bacteria numbers are high. The interpretation
of the tests showed very low to nonexistent bacteria and this may explain why
no outbreaks of disease, infections and why the longevity of my animals using
the Anoxic Filtration System is so great.
