Ok, sorry bought that, I got the nitrates and nitrite names mixed up, but the results are the same. Your pond has to cycle, cleaning your entire pond will destroy what good Aerobic bacteria has established IN the pond, (or letting it dry out) those portions will now have to regrow. Yes you do have the colony in your filter, which is a good thing, but I'm afraid that will not be enough for even the 50 you have left. Stress plays a Huge part in a fishes health. Just like there is bad bacteria Always on OUR bodies, there is Always bad bacteria and parasites in a pond; no matter how much you filter or how clear your water is they will alway be there WAITING. Stress ie: low oxygen, over stocking, over feeding, introducing new fish before quarantine, hot weather, too much rain; these things and more can compromise your fish..... Mother Nature can be a B***h, and she will correct things if we don't.

I would be interested, as is Dave, to know if the dealer did do a scrape and what, if anything did he identify from that. I know that loosing fish is awful, but we need to take a deep breath, take a step back before reacting and get some facts. Then treat. Yes, you want to stop the fish from dying, but treating hurriedly, could result in the wrong decision and will then delay the correct treatment.
Also, when you say koi dealer, is this a person that is a specialist in koi; or even fish in general, and no just a pet food center that sells animals? I'm not saying ALL pet food centers do not know what they are doing ( although I have found no one in my area that doesn't use the strips for testing pond water) but let's be honest, most don't and do not have the tools to diagnose what is wrong with your fish.
I'm sorry for your loss, and wish you well in saving the rest of your fish. And please, when everything settles, thin the herd?

yes I have two nine inch air stones with a matala aerator the purple is dried on the sides and bottom of my pond and no it has not been treated with anything. the pond only has 10% water in it
I have no idea what the "purple" is, but hopefully someone else does and can contribute. I'd be worried, too.

I use a Koi guy that has had Koi for over 25 years and selling them making ponds etc. He has never seen this purple stuff before so I need some help here.

My pond guy has never seen it before so it worries me that maybe somebody put something in my pond. My fish have been healthy all along and everything was good until friday I found two dead fish, but they was about an 1 long so did not really concern me much because of them being so small. But I change 25% of the water friday and sat was great but when I woke up sunday to 4 big fish and a bunch of little ones I went to my pond guy with one big fish and water. He gave me proform-c and told me to dump 90% of the water and refill and use it. I told him I had a 300 gallon tank he told me to put all the fish is there and start treating them so I did. I have only lost maybe 6 fish since. They are all swimming around and look healthy but some of them lost scales and fins. I test my water all the time at the same time of day. I just dont understand. Most of the fish in my tank are 3-4 inches long I have maybe 16 fish that are 6-7 inches. I just don't understand and it seems nobody else does either. I have been on this computer since sunday doing research and nothing looks like what my fish do.

Brenda would you like to be able too be self sufficient in taking scrapes etc? if your answer is yes then your going to need a nice microscope, slides and fixers we own a Bresser NG x 40 - x 1024
Microscopes are easy to come by on Amazon Turtle Mommy now does her own and is now able to anethatize her fish thanx to threads weve posted and is very keen to learn more.
Weve done thread on the forum of how to take a scrape , once learned its very easy to do.
Question Brenda Is the Purple as a result of the treatment used in the pond ?
With only 10% of water in the pond when you fill it again it will most probably have to go through a cyle which will be rough on the fish perhaps add only one or two of the strongest to get things running again.
Question these purple patches dried onto the sides of the pond is what you have been using Potasium Permanganate under a different name , it comes in a purple crystal ?


Dave
Nothing has been put in the pond that has K+ in it nothing that is purple I have ordered a microscope its not here yet. I know that I have to cycle again when I fill it but I don't know how much cleaning I need to do to it first until I know what that purple stuff is. I am worried that maybe somebody put something in my pond just not sure. I am going to add the fish that look good back in the pond a few at a time until it gets going. I have never treated pond with purple stuff. I will get all the names of stuff that I have put in when I get back I need to take my mom to doctor.

Look again at the staining Brenda see in the right hand corner how the staining goes to green , I really have a feeling that this purple staining must be somthingto do with algae .
Going back to the photo of your koi we see fin rot in the tail which would be indicative of Columnaris disease (Fin rot Gll rot Mouth Rot/Cotton wooland Skin columnaris) all come under ths headiing , I think the purple straining may be throwing us all off here , what do you think ?
I'm going to have a chat with our own clubs Koi Health official about the possible cause of the purple staining and then get back to you if thats ok ?

Yes I feel that is something different. I seen that today on a fish was am not treating and I am getting the pond going so I can get the ones that look good back in it. And when can I start to treat for that.

What my problem with that is there is not sigh of cotton mouth. I am wondering if it's not some kind of worm. I had today some white blue long skinny things in the pond. I took what I could get out we will see later what I find. and the gills are pink

Did he know how many fish you had in your pond? Do you use and IonGen? Too much copper?
