Re: PLEASE HELP
Ian,
Your pH is too low, should be in the range 7.0 - 8.5, this will be affecting your ammonia reading, you will need to buffer this up using this product,

For sure that low pH will kill your koi.

Re: PLEASE HELP
Hi Ian,
Stop doing water changes!!!! Everytime you do one you are killing your filters bio side, i know there won't be much at this time of year but every little helps. As Dave says low ph will kill fish, carry on with the buffers and monitor. Remember Test kits wont work at these low temps so take a water sample inside to warm up then do them. Would also strongly suggest you don't mix fish until you know the answers.
ps. Also did you fill pond using water purifier?

Re: PLEASE HELP
Hi Ian,
I'm sorry to hear about the fish, i couldn't do you a scrape as i don't feel i'm well enough qualified, however some of the other club members are more qualified and might contact you to help. I think without a scrape you would be struggling to find out exactly the course and hence the correct treatment. I know the Richdon web site has a wealth of information that might help ( if the moderators don't mind me mentioning them) and this could be your next plan of attack to see if something similar has been mentioned on their site.One last option would be to try and located a tank or container large enough to turn into a ''Heated'' QT which would give you much more control over the situation however you would still need a scrape done to know what to treat.
Hope it works out for you mate, Mitch.

Re: PLEASE HELP
Hi,
I do not see the advantage of taking a scape at this time, because what ever parasite you find if any, you would not be able to treat as the water temp is too low. The lowest you can go is 45degF (7.2degC) with PP. A heated QT is the way, but this has to have fully mature water and filters other wise you will stress the koi.
If no new Koi were added to the pond prior to the problems, it is more likely to be a water related problem.

Re: PLEASE HELP
Ian,
Reading your posts I would suggest that the high Am level, although very undesirable, is not the cause of the koi deaths but it may have been the low pH levels.
In the tables I have, for a pH of 6.5 and a temperature of 10C the total Am reading (This is what is measured by the test kits) would have to be above 30 before it would be harmfull to the koi. This is because at low pH and temperature levels the ammonia takes the form of Ammonium NH4+ which is much less toxic to the fish than the free Ammonia NH3+ present at higher pH and temperature levels.
This link to the koiquest website gives a fuller explanation.

As Dave has already said at the present low temperatures all the common pond treatments are ineffective,
