As spring transitions into early summer in Georgia, your pond will begin to thrive—but it also requires attention to stay healthy. Here are some pond care tips to keep your aquatic environment in top shape this May:

​

Monitor Water Temperature and Oxygen Levels
As temperatures rise, so does your pond’s biological activity. Warmer water holds less oxygen, so it’s important to ensure proper aeration. Check that your pumps, waterfalls, or aerators are functioning well.
 

Begin Feeding Fish Regularly
Fish become more active as the water warms above 55°F. You can now resume feeding your koi and goldfish, but use a quality warm-weather or spring blend food. Avoid overfeeding—feed what they can consume in about 5 minutes.

​

Watch for Algae Growth
Longer days and warmer temps can lead to algae blooms. Keep your pond balanced by maintaining good filtration, using beneficial bacteria, and avoiding nutrient buildup. A UV clarifier can help control green water.

​

Add or Maintain Aquatic Plants
Water lilies, water hyacinth, and other floating or marginal plants help shade the pond and reduce algae. May is a great time to plant or divide hardy aquatic plants. Floating plants like water hyacinth help with nutrient control and provide cover for fish.

​

Clean and Inspect Filters
Check your mechanical and biological filters to ensure they’re clean and functioning efficiently. A clogged filter can reduce water quality and circulation.

​

Perform Partial Water Changes
A 10–15% water change every couple of weeks helps maintain water quality. Always use a dechlorinator when adding tap water.

​

Check for Leaks or Low Water Levels
Warmer weather means more evaporation. If you’re topping off your pond too frequently, inspect the liner and plumbing for leaks.

​

Keep an Eye on Fish Health
Fish are more susceptible to parasites and disease in spring. Look for signs like flashing (rubbing), clamped fins, or sores, and treat early if needed.

​

Prepare for Summer Heat
Now is the time to set your pond up for the hotter months. Add shade with aquatic plants or shade cloth, and consider upgrading your aeration system if needed.
