    Tx new Kaldnes K1 & Biochips w/ Potassium Permanganate (PP)

    I finally finished installing my two Nexus 300 in my outdoor pond and was wondering if any of you have ever dipped new K1 Kaldnes & biochips in potassium permanganate to speed up bacterial seeding time. If so, then what concentration of PP did you guys use and how long did you guys dip the K1 Kaldnes and/or biochips in the PP for? Also, did you guys see a faster result in bacterial seeding time?

    Hello Lam . . .

    Yes, I've read about using PP to 'etch' the surface of the plastic to facilitate adhesion of the bio-bugs to the plastic; I've also read that it's not necessary and won't speed up the process (JR maybe?).

    Sorry to be of so little help.

    Thanks Don. I have heard both extremes of using PP to remove the plastic or roughen the surface of the new K1 Kaldnes to make bacteria adhere faster. Some folks who attended the PNKCA convention said that Jasper Kuijper said that using PP alone doesn't really help and that it is only effective if 3 components are used: dip in PP, adding a high concentration of proteins (some say to crush high protein koi food and sprinkle it on the Kaldnes), and a 3rd agent/step that I can't recall.

    Just curious to hear from folks who have used PP on their new Kaldnes and whether it helped w/ seeding time. I know that it took forever (~3mos) for the Kaldnes in my Nexus 200 in the QT tank to mature. In addition to possibly treating the Kaldnes w/ PP, I will also be moving some of these mature Kaldnes to the two Nexus 300 as well.

    Lam,
    On my "Carboard Box" pond (Modular pond system) I always run about a 1.5 ppm concentration of PP through the entire system (including the Nexus) at start up (prior to koi). I find that it still takes about 6 weeks for cycling.

    Hey Lam,

    Looks like you already have your answer, but I'll throw in here as well.

    I haven't PP'd my kaldness, but when I added a new filter to my system, I put half the new kaldness in to the new filter, and put the other half into an established filter, and then of course pulled approx the same amount out and put it in the new filter.

    Total time before their color was consistent was like 3 weeks or so. Seemed to go really fast.

    Worth noting, this was to seed and get an aerated filter going. Might be different if static....

    New K-1 doesn't want to fluidize very well. Soaking it in PP will remove the film on the new media and speed up the fluidizing process but I don't think will do anything to speed up the growth of bacteria.
