Winter to Spring pond & fish! Seasonal Care made easy. Read On

Winter to spring is an exciting time for koi and goldfish enthusiasts because spring marks the start of the fish year. Your fish, on the other hand, will be at their lowest point; the fat reserves built up during the previous summer and autumn to tide them over the winter will have been depleted. This, combined with fluctuating temperatures, puts your fish at risk of infection. Bring the fish to the surface with our floating wheatgerm and algae food so you can inspect them and look for any issues.


The water temperature will be around 7 degrees, and the fish will be restless. At this time of year, make sure to provide easily digestible food, ideally including wheatgermspirulina, carbohydrates, and live foods like chopped earthworms.

If you change the food too soon and start feeding the fish more indigestible foods (higher protein) during a cold spell, they will be carrying half-digested food in their intestines, which can lead to inflammation and disease. 

When the water temperature reaches 13 degrees, you can begin feeding a high protein food, mixing it with our wheatgerm floating pellet. 

When the water temperature is 19 degrees, all fish can have high protein levels. This is the time to start feeding foods like hikari gold for growth and colour.


It is a good idea to drain or back-flush your filters before the bacteria begin to proliferate in the rising temperatures. If you dont have a back flush option clean the filter sponges and media in a bucket of your pond water in preparation for spring, start doing maintenance in late August. Don't be tempted to go overboard; you don't want to destabilize the pond right now. 20% Water changes, filter backwash & clean out the bottom of the pond.


Because the plants have not yet grown strongly, filter activity is low, and sunny days will encourage the growth of algae feeding on the nitrates that have accumulated in the pond from winter rains, expect 'algae blooms.' Do water changes once a week before spring in August. Algae killer should be used to treat an algae blooms. Clear the pond's bottom of all debris and muck that has been washed in by the rain. If you clean the bottom, you will see less pea soup and more of your fish.


Re-pot any plants you have now! The rest of the pot should be river pebbles, as the nitrates in the water will provide the nutrients for the plants to begin growing. Plants go dormant during the winter, but once the weather warms up, they come back to life.
