At our state of the art CEFAS approved facility at Banstead, Surrey, when heating a Koi pond, we at Koi Water Garden feel it is important to give the fish seasonal fluctuation in temperatures. The following table has been compiled after 30 years of personal research into heating Koi ponds.

By Following these temperatures and feeding regime you will give your fish both maximum health and growth prospectively.

IMPORTANT: Ideally increase/decrease temperature by 1’C per week

Never increase /decrease temperature by more than 1’C per day unless in an emergency. When heating a pond

continue with normal summer maintenance routine.


Winter feeding Notes:

·        Only feed Wheatgerm/Multi-season in the mornings and when fish are actively looking for food.

·        At low temperatures do not feed if the fish have no appetite, or during cold severe weather.


Summer Feeding Notes:

·        Ideally feed the fish little and often

·        Only add the amount of feed the fish will readily consume within 5 minutes.

·        Feed up to 8 times per day providing the fish feed readily and the filtration is sufficient to keep the water quality in perfect condition.

·        Test water quality at least weekly for Ammonia, Nitrite and pH (keep a record of this)
