Welcome Cracker123.
How high is your ammonia, what chemicals have you used, what is your fish population (number of fish and size) and filtration?
Also, have you tested your water for any other parameters, including temperature?

And I'll ask for the one thing we always ask for - pictures! We love pictures!

Hi there I have about 6 koi largest being about 6lb in weight and now only about 10 goldfish about 6 inches in size. Ammonia level on the dip sticks is constantly 6.0 very high despite numerous water changes with pond start to combat tap water. Temperature is about 10 degrees and I use a filtering with built in uv light which has been good for years.

quilt batting in a crate with a pump in the pond with a hose from it running into the crate will help also .I use that when I have any problems

The Pond Safe you are using is only effective for 24-48 hours, but if your pond is 15 years old something has seriously gone wrong.
Is this a recent development?
Could some animal have fallen into the pond and died?
How long did the dead fish remain in the pond before they were removed?
Could some pesticide or herbicide have gotten into the pond water?
Test strips are not very accurate and 6.0 is the maximum that some test strips measure up to.
Is there any physical appearance you can see on the dead fish that could indicate the cause of death?
Post a picture of the dead fish if you can.
Other water test parameters would be helpful, from liquid drop test kits, not test strips.

pet stores have it and you can get it online ,not sure what you have there .But I agree with Mitch ,something caused this and you will need to find out what it was .But at least you will get it down some for fish safety .Do you have aerator in the pond and what kind of filter .I have koi and have 2 stock tank filters and 12 airstones ,koi can get stressed .Are you feeding them ,stop now ,no more food until you get it down API liquid test kit is better

Been about a month but if you're still having ammonia problems when I set up a new pond I was having ammonia spikes make sure you check the pond for any kind of dead animals or fish I purchased Eco Labs NITE32 microbe lift Nite out nutrify bacteria 32 oz I kept playing around with the ammonia spikes and nitrite and I just decided to dump the whole bottle in fix the problem instantly. Didn't have any further problems after that.
