      Rodney, thanks for all your help over the years. I am currently dealing with a few lethargic koi in my 3800 gallon, 26 year-old pond. I only have 5 koi but they are all pushing 30" or more. My oldest is 32 years old. The others are all 15+ years old.

      I don't spend much time on koiphen but its always my go-to site for filter upgrade ideas and koi health problems. In the past when I've had koi health problems, I've turned to PP. I came back to koiphen this yesterday to see if there were any updates to your PP protocol. I read thru this entire thread twice over the last two days. I decided to do a 2 ppm treatment every 4 days over the next month to (hopefully) squash what the pest might be. I generally try to avoid pulling fish. It's time consuming, heavy work (about 20 lbs each), hard on the koi and in the end I almost always reach for PP anyway because its so broad spectrum. I'll monitor the fish thru the process. The first dose turned brown after 2 hours so I redosed with another 1 ppm dose. The second dose turned brown after 3 hours (5 hours total). I think that's an indicator of how clean I keep my pond. I'll add HP in an hour or so and plan on redosing in 4 days from now.

      I also appreciated the water regeneration ideas using PP. I read about that years ago but with the persistent low rainfall in California, anything I can do to save water is a worthy exercise.

      I truly appreciate your scientific approach to the PP treatment. I don't have enough chemistry understanding to follow the chemical processes but appreciate that you do and share your knowledge so eloquently and your time so generously. I also have a PhD (electrical engineering/mathematics) and went to USC engineering school as an undergrad. You're 1/2 generation older than me. I worked with a fellow that also got a PhD (electrical engineering) at USC about the same time you were there. He studied radio propagation and antennas. I know you weren't doing that but perhaps you cross paths with him: Ken Brown.

      I truly don't understand some of the nay-sayers in this threads. Legitimate discourse is helpful to everyone so we can all grow and understand, naysayers with (what appears to be) a vendetta are unhelpful and nasty. I generally skip over their posts. It always boggle my mind trying to understand why they bother. Thank you for keeping it civil.

      Cheers! Miguel (on the central coast of California)

      Hi Mr. Roddy Wish you had a good health and longevity, your method are great for this hobbies. In my opinion thie method not only saving water bill, it ensure water are clean and save for koi. You also contribute for decreasing global warming if every one is following you. So thank you Sir..
      I did your method for around 3 month now. Not consistent as 4 day you mentioned, sometimes once a week sometimes once every two week. But the koi has significant growth.
      But only pp without malachite green.
      As i'm struggling to get here in Indonesia. The only one i can get is Malachite Green Oxalate. If i wonder is it the same.

      Then one more thing as i read from your post you didn't mention about dosage or ppm for formalin and mg or i missed.
      Can you tell us here how much do you use?

      Hi Noviardi,
      I was also looking for the dosage rate, he did mention he used the dose rate as per prescribed amount, I did a google search and came up with a rate of 10ml per 1000L in temperatures below 14 degrees c or 10ml per 500L for above 14 degrees c, I don't have access to MG. if anyone has a better (tried and tested) dose rate please post.
      Regards

      Are you talking about a dose rate for a PP treatment?

      Dose I got based on the initial post was:
      28g (1 Oz) per 2000 gallons(7580L)
      Neutralize with ~250mL (8floz) of 12% hydrogen peroxide

      I've treated with this rate a couple times without any issues. Ran outta H2O2.

      As long as you follow directions, and understand what you are doing, then it can and will be safe to use.

      Wear your personal protecting equipment (safety glasses, gloves).

      Know your pond gallons, then follow the directions. I use a scale to measure the PP, and have enough hydrogen peroxide on hand.
