Preparing Your Ecosystem Pond for Summer

As the days get longer and warmer, your ecosystem pond is ready to come back to life. Fish become more active, plants start to grow with vigour, and your water feature becomes the relaxing centrepiece it’s meant to be. But before you kick back and enjoy those peaceful summer evenings by the pond, it’s important to make sure everything is in top shape for the season.

Here’s our guide to getting your pond summer-ready the right way — without stress, and with plenty of time left to enjoy it.

1. Do a Spring Clean (If You Haven’t Already)

If you haven’t done a spring clean-out yet, now’s the time. Remove built-up debris like leaves, excess sludge, and anything that’s settled over winter. Too much organic matter breaking down in the pond can lead to murky water and algae blooms once the sun hits.

Pro tip: If your pond is in decent shape, a full drain and clean might not be necessary. A partial water change, netting out debris, and cleaning your filters may be enough.

2. Check the Filtration System

An ecosystem pond relies on its filtration system — especially biological filters and skimmers — to keep water clean and clear. Make sure everything is flowing as it should:

• Rinse your filter pads with pond water (not tap water)
• Clear out the skimmer basket
• Make sure your pump is running efficiently
• Check the plumbing for any leaks or blockages
• If you use additional equipment like UV clarifiers, now’s a good time to check or replace the bulb too.

3. Reintroduce Beneficial Bacteria

Once your water temperature is consistently above 10°C (50°F), start adding beneficial bacteria. This helps kickstart the biological filter and supports the natural breakdown of waste in your pond.

We recommend using high-quality products like Aquascape’s Cold Water Beneficial Bacteria early in the season, followed by their regular bacteria blend once things warm up.

4. Feed Fish Properly (And Gradually)

Fish metabolism speeds up as water warms — but don’t rush it. Start with easily digestible spring fish food and gradually switch to summer formulas as the temperature climbs.

Avoid overfeeding: uneaten food contributes to poor water quality, especially in warmer weather. As a general rule, feed only what your fish will eat in about 2 minutes.

5. Prune and Plant for Summer Growth

Aquatic plants are vital in an ecosystem pond. They shade the water, reduce algae growth, and help balance the system naturally.

• Trim back dead foliage
• Replant or divide overcrowded plants
• Add floating plants like water lettuce or hyacinth for extra shade and nutrient uptake

If you’re looking to boost your pond’s plant game, we’re happy to help source and install the right mix for your setup.

6. Watch Water Levels and Top Up as Needed

Evaporation increases in summer, especially in shallow ponds or those with waterfalls and streams. Keep an eye on your water level and top up with dechlorinated water when necessary. Installing an automatic top-up valve is a great hands-off solution.

7. Be Proactive With Algae Control

Warm water, long daylight hours, and nutrient build-up can lead to string algae and green water. Prevention is the best cure:

• Keep up with beneficial bacteria treatments
• Maintain plant coverage (aim for 60% surface coverage)
• Skim out organic debris regularly

If algae becomes a problem, we can recommend natural solutions that keep your pond in balance — without harming fish or plants.
