Rotting vegetation may become a problem if your pond is covered with ice. The reason for this is that the gases given off are unable to escape into the atmosphere. This in turn will have a detrimental effect on your fish.
Should ice cover your pond then do not attempt to break it as the shock waves can seriously harm your fish. A simple solution would be to half fill a pan with boiling water and place it on the ice to melt it. This should be done on a daily basis to allow the escape of methane gases.
When water temperatures are below 10° C the feeding of your fish is not necessary. It is not only wasteful but uneaten food will pollute the water.
There is very little else to do during the winter months as fish become semi-dormant and remain close to the bottom of your pond.
SPRING
Check to make sure that pump and filter systems are working correctly and replace UVC lamp if necessary. The feeding of your fish can be resumed once temperatures have risen to approximately 12°C. This should be a gradual process.
Be sure to remove any algae using either a skimmer or any other suitable tool.
The introduction of new plants can also be undertaken during the early season.
Do not be tempted to remove netting from your pond as your fish are still at risk from Herons and Kingfishers.
Now is the time to begin closely monitoring the condition of your fish for any possible ailments.
SUMMER
A time to enjoy your creation but also a busy time!
Pumps and filters will need constant monitoring because of the possible growth of algae and blanketweed. They will need to be cleaned on a regular basis to ensure optimum performance.
Ensure that water is well oxygenated as this will benefit the fish especially during hot spells.
Do not be tempted to top up your pond with tap water on a regular basis as this will only intensify the risk of algae due to the added chemicals.
During extreme temperatures monitor your fish closely as oxygen levels may fall especially at night. This will distress your fish and in turn affect their health.
During the Summer, water levels may fall considerably due to evaporation. This may lead you to believe that your pond is leaking when in actual fact, it isn't.
AUTUMN
At this time of year, plants in your pond will begin to die back and rot and if left unattended will cause pollution. Cut back any dead or dying material and thin out oxygenating plants.
Use a net to gather any debris from your pond to reduce the risk of pollution from rotting vegetation and
Place netting over your pond to help prevent falling leaves from entering the water.
This is also the time of year when you should be reducing the feeding of your fish and paying attention to their health.
Lengths of piping suitable for the size of your fish can be placed in your pond to give them shelter.
As with any other season, it is advisable to maintain periodic checks on your pond.
