SEASONAL CARE
     
 
     
   SPRING
 

As the water temperature rises above 6 degrees centigrade the fish can be fed sparingly with low protein foods to aid digestion which may be slow after winter hibernation.

The fish can be inspected for any clinging parasites they may have picked up. These should be identified and dealt with accordingly.

Re-pot or divide plants as necessary. Move lilies nearer the surface to speed up growth.
Introduce any new fish but check that you don't have to many for the pond size, as a guide for each square foot of surface area of the pond 2-3 inches of fish may be kept.
Allow for fish growth, especially Koi Carp which double in size yearly for app 6 years.
 

 SUMMER
  Top up water lost through evaporation adding the correct amount of anti chlorine solution if using tap water.

As pond temperatures rise, the oxygen level will fall so if the fish are seen gasping at the surface action must be taken. As an emergency measure a jet of water from a hose can be directed at the water surface. A permanent solution such as a waterfall or fountain should be considered.

Remove any dead leaves from the pond. Thin out plants as necessary to avoid them choking the pond and keep control of blanket weed by removing by hand or twirling round a stick.

There are devices on the market to control blanket weed such as magnets and chemicals but they don't work that often. The nutrient/ph level of the water is usually the culprit, and there are kits to test for incorrect levels - but it all gets rather complicated. Watch out for dead frogs in the pond as they will cause the water quality to rapidly deteriorate.
 
 AUTUMN
  Keep fallen leaves off of the pond with a net stretched over it.
Pine needles produce tannic acid which is harmful to fish, finer mesh is needed to stop these, something like net curtain.
Continue feeding the fish as much as they will eat in 5 mins. Give a wheatgerm type food as the temp drops and metabolism slows.
At the end of the season trim back growth on lilies above the crown and lower to deeper water, other semi hardy plants should also be lowered to prevent icing up.
 
 WINTER
  Unless the pond freezes solid keep the pump running but raise it to within a foot of the surface so as not to disturb warmer water at the bottom of the pond where the fish live over winter
To prevent the pond icing over use a pond heater which floats on the surface and keeps a hole free from ice.
Do not ever crack ice forcibly as this can shock the fish. A pot of boiling water may be used to melt through the ice.
Stop feeding the fish.
