KOI CARE THE FIVE MOST COMMON CAUSES OF SICK KOI

Every day I receive many requests from koi pond hobbyist across the country for help with their sick koi. I would like to share with you the top five most common causes of sick koi.

1. Poor Pond Water Quality: 70% of all koi sickness is caused from poor pond water quality

• Filter not large enough for the size of the pond

• Not enough aeration: falsely thinking if you have a waterfalls, it’s enough aeration. The Importance of Aeration

• Not doing partial weekly pond water changes

• Not doing weekly pond water testing for ammonia, nitrites and pH

• Over cleaning your filter and filter media killing all the “Good Bacteria”

• Cleaning your filter and filter media with “City Water” that contains chlorine which kills all the “Good Bacteria”.

2. Not quarantining new fish: VERY IMPORTANT!!! How to Quarantine your new Koi:

3. Over Feeding

4. Over Crowding How many fish will my pond hold?

5. “Chemical Soup”: having sick koi and adding every medication you read about to your pond

Just by correcting these five common causes, you can keep your koi happy and healthy.
