Summer provides the perfect conditions for an algae bloom – excess nutrients in the water, plenty of hours of sunlight, and warm temperatures – so this is the season to be vigilant about algae prevention. We worked with some of the best pond maintenance professionals to bring you insider tips on summer pond care.
Koi pond care in the summer can be tricky and sometimes string algae can seem to spring up out of nowhere. There is always a reason why ponds have difficulty and usually there is no quick-fix. Patience is a virtue when it comes to this hobby and a knowledge of water chemistry is a must. We’ve asked our partners for some tips and included our favorites below.
Tip 1. Maintain High Oxygen Levels
“Adding an aerator or waterfall to your pond can help keep the oxygen level up and assist in long-term algae maintenance. Choose based on your pond’s size – too small an aerator won’t give the oxygen it needs and one made for larger ponds will be a waste and could lead to oxygen supersaturation.”
Tip 2. Test Water Parameters
“We suggest testing water parameters at least 2 to 3 times a week for the first month when you start the practice of testing. This allows you to get to know what is normal for your pond. Once you have your pond “figured out” you can test once a week.”
Tip 3. Vacuum Pond and Remove Brown Plants
“Use a Pond Vacuum for Spring Pond clean up and CrystalClear Muck Off which helps to eliminate sludge build-up in the bottom of the pond. I recommend that water plants be maintained throughout the season – dead heading, and if it’s brown, cut it down!”

Success for pond care in the Winter really begins in the autumn, when temperatures start to drop, leaves fall from the trees, and plants and animals start preparing themselves for the winter. Because seasons can differ dramatically across geography, especially in large countries like the U.S. and Canada, there is no set time to start your fall maintenance routine. Rather, keep an eye on the weather, water temperature, and surrounding environment.
Tip 1. Relax, enjoy, the season and do not bug your fish.
“As the water temperature drops, fish require less and less food and become increasingly inactive. Once the water temperature reaches a consistent 50 degrees F, you won’t need to feed your fish at all.”
Tip 2. Algae can survive freezing temperatures.
“The cooler temperatures of fall also mean a change in how you treat algae. Even in freeze zones, there are still types of algae that survive. To keep a healthy balance in your pond, keep treating it with Nualgi.”
Tip 3. If the pond surface freezes over do not bang on it or try to chip holes in it.
“The vibrations are dangerous to fish. Instead, use this tip from Sparks: “Heat water in a pot and set the pot on top of the ice; the hot pot of water will melt through the ice creating a hole. Remember to tie a string to the pot or it will be at the bottom of the pond.”
