What you’re about to read is the water parameters of a pond after a bombardment of chemicals far the past five days followed by feeding medicated fish foods for insurance purposes.

On April 25th I posted about a hobbyist that introduced a “ Typhoid Mary” Koi to their pond. You can read more at the link below.

They were very worried about the AFS and any chemicals that were to be administered to their pond and would it harm the BCB’s filtering capabilities, Potassium Permanganate and Acriflavine were the two that are mentioned in the article.

Also, another hobbyist inquired about the same thing from Florida and asked if Potassium Permanganate KMnO4 (PP) and Hydrogen Peroxide (HP) would be a problem with the bacteria residing in the BCB’s because both of these chemicals are very strong oxidizing agents and if administered in the wrong quantities will have a devastating outcome to your animals.  When using Potassium Permanganate you must know the exact amount of water in your pond or overdose may have a very negative consequence on water parameters. Read more on link below:

These questions are not unfounded, because, and I will quote here: “I never got this good of a reading (After medication has been used.) even if I have fasted the fish for 10 days with frequent water changes and daily mechanical filter cleanings with a conventional filter.”

Most of us have been down that road to perdition when a pet of ours comes up sick and now will the evasive action we take be enough to save it from the clutches of death. When it comes to fish, the problem is twofold because not only are we trying combat the infection or parasite but water parameters are also being affected by the chemicals we use. If the treatment goes on far too long, them water quality become compromised to the point it may prolong the recovery process or worsen the animals in question with secondary infections. Then on top of all that comes the disintegration of the biological filter to the point Ammonia and Nitrites may even reach deadly levels.

What you’re about to read is the water parameters of a pond after a bombardment of chemicals far the past five days followed by feeding medicated fish foods for insurance purposes. If you’re one of the lucky one that has never been through medicating your fish, then count your blessings. It’s very expensive and nerve racking because you hope none of your animals die. Been there done that, right! Well it sure is nice to know when you can count on your filter not to let you down in these situations. Research has shown that the AFS is one residual filter when it comes to chemical treatment. One reason is the heterotrophic bacteria can multiply into trilliums of cells in a matter of hours and not days like nitrobacteria take. This shorter recovery time of the cells is what hobbyists are looking for, especially after prolong medicated treatments of PP.


Dear Dr.Novak,

I have completed my pond treatment on Sunday, so for a recap I have treated the pond with one treatment of PP with a dose of 2gr/ton and 8 applications of Acriflavine in the morning and afternoon.

On Monday I gave the pond a dose of clay, hoping it would help clear out any medication residue. Starting Tuesday I started feeding the koi medicated food in the morning and afternoon. Today I started feeding them normal koi food still mixed with a little medicated food.

Last night I tested the pond parameters to see whether the BCB's are still working, and here are the results:

Ammonia @ 0
Nitrite @0
Nitrate@ 0
PH 7.8
TDS 56
Temperature 26° C
ORP 500

I hope this is an indication that the BCB's survived the whole medication treatment. I think I can get "undetected" for nitrate now because maybe more of my BCB's have become mature, I hope. At least these results would put me at ease when I have to leave town for work.

Best regards,
