I’m starting to keep koi,have a 2000 gallon outdoor tank. My test results according to API master test kit is,
Ammonia 0
Nitrite 0
Nitrate 0
Ph is 8
I did have a small nitrite spike but used prime until it was back to zero.
All fish were purchased from NDK,which I am now finding out was a mistake. I have lost one fish already,but I think that was in part to me being new a d mis using treatments. Already done the Pima/Melafix waste of money!
I have used BSDT (malachite green and Formalin one treatment. And did one Prazi treatment.
Have done 3 50% water changes using prime along with water filter as well on refill.
It started with one fish getting a red spot,then same fish mouth rot,and then same fish died,but I think it was partly my fault on using PP dip that was too strong!
Now one fish has a large sore getting worse daily,and have noticed another fish starting a small spot just as the others started.
Any help,tips,methods please fire away!!
I do t want to loose all my fish.
The only thing I have not tried yet is a lot of salt,I’ve only used 2 cups,the salt just bothers me,but I’m sure I need to get over it!
Will try to figure out how to post pics ASAP!
Thank you all in advance for your help
