      Koi disoriented, heavy gasping

      I have a tosai koi that is swimming around erratically very disoriented, heavy gasping. does nt appear to have any injuries after hands on inspection, gills are dark red, no obstruction in its mouth. rest of the herd are doing fine.

      Here are the water parameters as of last night
      ph - 8.2
      nitrite - 0
      amm - 0
      KH - 150 - 180
      nitrate - 80

      my nitrate has been around 80ppm for most of the summer but I do water changes every other day. Pond is about 2000 gal, each w/c is 150gals or so. I have an aerated BD that is running all the time. I have pulled the automatic feeder.

      I have performed two treatments of BSDT, one last night and one this morning, each after each w/c. I have been double dosing with seachem safe prior to any w/c plus running through a water filter (boogie plus). After the second treatment, I noticed that one of the largest koi flashing and I would say that is from the treatments as no fish was flashing last night after observing for 15mins.

      I have an external water pump which I dont believe the issues are not electrical shock related.

      Only thing that make sense is some sort of poisoning. I have a house plant call Purple Heart growing in my waterfall. After reading online, it says it is toxic if consumed. The koi are not able to get to the plant but I did notice two days ago a leave of it ended up in my cetus sieve. The plant has been removed that was making contact with the waterfall.

      Thanks for any help.

      Just a possibility...

      Can you overdose Seachem Safe?
      FAQ: Is it possible to overdose Seachem Prime®? Prime® is very safe and quite difficult to overdose to the point of harming tank inhabitants, but a large enough overdose can start to deplete the system of oxygen.

      are you sure you are not dosing too frequently? Also when you dose you need to spread it out so you avoid high concentration exposure to the fish.

      I'm assuming the water went clear before redose?

      I added 50lbs of salt to the pond, the koi immediately responded and as of this morning acts like nothing had occurred. Also added an addition 8in disk aerator. The TDS this morning was 1275ppm.

      Should I bump the TDS up to 3000ppm? Should I treat with Fluke-M, maybe there is something internally going on?

      Thanks

      If the fish are not exhibiting any distress, I would do nothing. If strange actions occur, let us know.
