      Yes. No redness from stress or anything.. I've added many fish over tlme and have been fine. Something is weird to me. None of the fish show ulcers etc but yet the new fish and my sanke and kikisui were flashing also yesterday and today. I think I should isolate these 2 from the rest of the herd.

      Sorry my friend
      I think
      Lower temperature hard for the new koi to boost immune system
      Also treatments play part of the role shocking the koi
      So yes have a heated qtank 24/365 days for the new comers

      Thanks bro. Yes it was just a bad deal. I thought weather would be better after proform-c and new addition and cold weather whooped me in the keyster. I need to get things under control and reduce my fish load asap

      Sorry Kevin... I guess thing happens sometimes and we will have to learn from it and do a better job next time.. Hopefully your remaining fishes are OK.. Try not to be panic and over correcting things.

      Start with a big water change. Don't dump stuff in, get the ph/kh right and scrape and scope. How long after you added did the fish die?

      For me, a KH of 6 drops is just on the low side. I would boost it up a little bit. When I add baking soda, I always add ammonia binder too, just in case. If your KH is 8-10 drops, you don't have to measure pH, as it will be in the range of 8.2, if you control with baking soda. And I agree, those marks on the belly look weird. Do you still have the dead fish?

      Also I'm just using a cell phone for the pics. We found several of these and didnt look like an air bubble or anything we have seen.

      I don't think this koi died from the trichodina if that is what is in slide. But between the stress and treatment. Huge amounts of rain etc... Just pushed this fish over the edge. It seemed to pretty much stroke out. Went sideways all of the sudden swam and stopped few times then was done. The other fish are not flashing today that I have seen and nothing was moving on the slide. So nice water change and getting ph pen tomorrow is best I can do. Weather is supposed to warm up next week so that will be good.

      Forgot to mention scraped 2 fish that were flashing yesterday and found this on both slides.

      1 more thing I did use clove oil to calm the fish. Didnt go under but enough to stay comfortable for the scrape. Have heard maybe the clove oil slows down the parasites also idk. But did use clove oil so just giving all info I can. Fish recovered very fast after clove oil also

      found hydra like this and the other stuff was around it.

      Didn't think much at the time and seemed algae. But found a Video with trichodina around a hydra. I didn't get a pic through microscope but did seem to see one of these on the 2nd scrape we did. Seems it can be nasty also?

      Those look like bubbles to me. But if you look at the first slide you posed, it looks like there might be something in the very bottom of the shot.

      Could have been air Bubbles. I tried to move the cover slip on top to see if it would go away. Nothing was moving on the slide though so I guess that it is a good thing

      Kikisui and my smaller ogon are flashing today.

      Ph is 8.5. Kh is still 6 drops api

      Since I'm over 8 ph I guess I can add a cup of bs per 1000 gallons until I got 8 drops of kh.

      I'm moderated on posting in er. I don't have the pond heated but I do have the means to heat it slowly which may be the best bet. I noticed a slight redness on belly of the 2nd koi we scraped. Seems more along the line of bacterial infection and could get worse. I'll order elbagin as this seems to have great results and seems to calm the fish.

      Water is 58 degrees today

      If your pH is stable and there is no chlorine or ammonia, then it pretty much has to be parasites. Some like costia are hard to see, even with a good microscope and trained eye. I would treat with Proform C 3 doses. The fish that died probably had some issue, not associated with water or parasites, like heart attack or stroke. Parasites would generally be causing serious flashing and wasting away, or ulcers to kill a fish and both would take longer then that fish took, and have more visible signs of damage.

      I agree. I did a 2x proform-c Thursday and Friday last week so can't really do a 3x again. I'm using fluke _m now to clear the fish more. I will check ph in morning but pretty sure I'm stable. I could possibly do a 1x proform-c next week as the weather will be in the 70 degree range

      Is the water warm enough for pro form C?

      He has heaters so he can bring it up to a workable pH if he doesn't already have the temperature high enough.

      I did on my 300 tanks for tosai rich. The pond was 55 degrees at best and I might have slightly overdosed the amount. I forgot my intex is really 1350 gallons at best and I dosed for 1500 and then we got pounded with rain
