How much and how often should I feed the koi?

 Feeding your koi is a major part of pond maintenance.  Always feed a high quality food with no fillers.  Cheap foods often have fillers that are not as digestible and cause more waste.  Most premium foods don't use fillers have are more digestible and therefore you will have less waste in the pond.  The frequency of the feeding will depend on many factors.  Time of year, number of koi, size of pond and quality of filtration. 

Koi do prefer to have more frequent small meals rather then one large one.  Just like humans, we don't eat one giant meal in the middle of the day, we eat three smaller ones.  Will we survive on one big meal a day?  Yes, but its not good for our digestion.  Koi prefer the same thing, several smaller meals during the day.  During peak summer temps you can feed the koi as often are 4 or even 5 times a day, assuming the filtration can hadle that much koi food.  If not, still feed multiple times a day, just use smaller portions.  You will find that the koi digest their food better and produce less waste, even if you increase to amount of food per day.

Generally speaking do not feed the koi if the water temps are below 50 degrees.  low to mid 50's you can feed very lightly, maybe 2-3 times per week and only a handful of food.  Upper 50's to low 60's you can start to feed once a day, but still small amounts.  Mid to upper 60's you can start feeding 2-3 times a day and above 70 degrees, feed as much as the filter can handle.
