Yogas and I have been communicating on his pond
and water quality for some time now. If you remember his old filtration system
was not doing the job he expected it to do and it was only at its precipice
of his ponds poor water quality that he decided to switch everything over to an
Anoxic Filtration System instead of buying an out-of-the-box-filter.
Yogas realized that water quality has many
stories to tell and test kits (Ones that tell you ammonia, nitrite, pH, and
nitrate.) will only tell you a small portion of that story. After reading my
blog he soon new that TDS, ORP and CE will also tell us more about water parameters
than just test kits alone.
His mission was to use the best filter he could,
add oxygen to his pond properly and make other small improvements to his pond
to give him über clean water. Well he has done it! Once again the AFS that has
low cost with high yield now buts him at the top of his game in Indonesia. I don’t think at any cost he could come
out with better water quality unless he spends thousand of dollars more. Those increments
of water quality would be very small indeed and in the long run would not justify
the extra expenditure.
As I have said before: You can spend more money
on filtration systems that are available to this hobby, but you really don’t
have to. If you want a filter with bells and whistles on it and don’t mind the
price them go far it! However, if you want a filter that works just as good or
better for a fraction of the price, then AFS is your forte.

[Ed: I just wanted
to add that an ORP of 300-375 is saltwater Mini Reef territory and is
considered to be Barr None the best of its class as for as redox goes. To see
this in a pond, only the über expensive filters can do this and most of the
time only with Ozone added.]

Hi Dr. Novak,
Nice to hear from you. I hope
everything is going smoothly for you. The chiller was installed yesterday and
begun cooling down my pond, not so much though. Right now its just set to chill
to 28 C. My pond ORP now varies between 300-350. I did the comparison towards
my water source. The ORP of my water source was between 350-370 while at that
time the pond ORP was around 300. Next week I'll try to further lower the
temperature to 26-27 C. My target eventually will be to maintain pond
temperature between 25-27 C. I'm quite excited about the effect 28 C has on
ORP, can't wait to see the ORP value at 25 C. I'm also very excited with what I can
know from this ORP monitor. In fact, I plan to use the ORP value to determine
when it is time for a mechanical filter backwash. Again, thank you very much
for all the enlightenment you have given to me, may God Bless you always.
Best regards,
Yogas
