Owning a backyard fish pond is one of the most rewarding ways to connect with nature, but the truth is, ponds are living, breathing ecosystems that need different care as the seasons change. If you want to keep your pond clear, your fish healthy, and your waterfalls flowing smoothly, you’ll need to stay ahead of seasonal shifts.
At Atlantis Water Gardens, we’ve been building and maintaining fish ponds across New Jersey for over two decades. From deep-freeze winters to scorching summers, we’ve seen it all, and we’re breaking it down so your pond doesn’t just survive, it thrives.
Spring: Wake It Up Gently
Spring is when everything comes back to life, but it’s also when most pond problems show up.
Start With a Deep Clean
After months of ice and debris buildup, your pond likely needs a reset. Clean out sludge, leaves, and leftover organic waste before temperatures hit the 60s. That rotting material is a buffet for spring algae.
- Use a pond vacuum or a net for debris.
- Do a partial water change (about 20%).
- Add beneficial bacteria to jump-start your biofilter.
Check on Equipment
Inspect pumps, plumbing, and filters for winter damage. Ice can crack fittings, clog lines, or jam impellers.
If you notice leaks or poor water flow, you’re not alone. We get a surge of calls every spring for fish pond repair in Randolph and surrounding areas, it’s a great time to fix things before algae season kicks in.
Test & Balance the Water
Check your pH, ammonia, nitrite, and nitrate levels. Fish are coming out of dormancy, and poor water chemistry stresses their immune systems.
Summer: Keep It Cool & Clear
Summer is pond season, koi are active, lilies are blooming, and waterfalls are doing their thing. But heat can turn your pond into a soup if you’re not careful.
Oxygen Is Everything
Warm water holds less oxygen. Make sure your pond has good circulation.
- Keep your waterfall or fountain running 24/7.
- Add an aerator if your fish are hanging near the surface or crowding the waterfall.
- Avoid overfeeding; excess food = more ammonia.
Watch the Water Level
Evaporation is no joke in July and August. Refill with dechlorinated water as needed and top off slowly to avoid shocking the system.
Algae Control
Sun + nutrients = string algae. Shade the pond with floating plants like water lilies, and stay on top of your nutrient load with regular bacteria treatments. UV clarifiers help with green water but won’t stop filamentous algae.
Fall: Prepare for Shutdown
Autumn is beautiful in New Jersey, but it’s also when the pond starts slowing down. This is your prep window for winter.
Skim and Net
Falling leaves are your pond’s worst enemy in fall. Net the surface or install a leaf net over the entire pond. This prevents clogs and water quality issues.
Switch Fish Food
When temps dip below 60°F, switch to a wheat germ-based food. It’s easier to digest and reduces waste. Stop feeding altogether when water is below 50°F, fish can’t metabolize it.
Trim and Remove Plants
Hardy plants can be cut back and left in the pond. Tropicals should be brought indoors or composted. Remove dying foliage, it breaks down fast in cooler water.
Winter: Let It Rest, But Don’t Ignore It
New Jersey winters can be brutal. A frozen-over pond doesn’t mean it’s time to forget about it.
Stop the Pump? Maybe…
If your waterfall is shallow or prone to ice damming, shut it down for the season and remove the pump. If it’s deep and runs cleanly through winter, you can keep it going, just monitor for ice damage.
Don’t Feed the Fish
Even if they “beg,” their digestive systems are dormant. Feeding during cold months creates toxic water conditions and can kill them.
Bonus Tips for All Seasons
- Schedule Regular Maintenance: Don’t wait for problems. A seasonal tune-up from a pro can save your ecosystem.
