Perfect AquaticsAt Perfect Aquatics, we’re passionate about helping you create and maintain a beautiful, thriving pond that brings you joy all year round. With spring on the way, now’s the perfect time to start preparing your pond for summer. A little care and attention now can make all the difference, ensuring your water stays clear, your fish are happy, and your garden becomes a serene oasis. In this guide, we’ll walk you through our top tips for a successful pond season.

1. Start Fresh: Clean Out Winter Debris
Winter can leave your pond full of leaves, sludge, and decaying matter, affecting water quality and fish health. Begin your pond maintenance by skimming surface debris with a pond net and using a pond vacuum to remove sludge from the bottom. A partial water change—about 10–20%—helps dilute toxins. Always add pond dechlorinator prior to adding fresh water when topping up or purchase a pre-filtration canister to prevent stress or long lasting damage to your Koi or other fish.

2. Balance Your Pond Water Quality
Testing water quality is a crucial part of spring pond maintenance. Use a pond water test kit to monitor pH, ammonia, nitrite, and nitrate levels. If readings are off, pond additives can help restore balance. Beneficial bacteria treatments are highly effective for breaking down organic waste and maintaining clear, healthy water for koi and goldfish.

3. Get Your Filter and Pump in Shape
A well-maintained pond filter and pump are essential for clear water and efficient algae control. Clean the filter media with pond water to preserve beneficial bacteria and check the pump for clogs or wear. Replacing old parts can improve water circulation, keeping oxygen levels high and preventing stagnant spots where algae can thrive.

4. Feed Your Fish the Right Way
As water temperatures rise above 10°C, your fish’s metabolism speeds up. Start with wheat germ-based koi food for easy digestion, then transition to high-protein koi food as temperatures increase. High-quality koi pellets support vibrant colors, growth, and immunity. Always look at the manufacturer's instructions to aid you in selecting the right food for the right temperatures so your fish thrive.

5. Natural Algae Control Solutions
Algae blooms can quickly take over your pond in warm weather. Use barley straw extract or UV clarifiers to manage algae naturally. Adding submerged oxygenating plants like hornwort or anacharis helps reduce algae growth by absorbing excess nutrients. Floating plants such as water hyacinths and water lettuce provide shade, limiting the sunlight algae need to thrive.

6. Inspect for Leaks and Damage
Cold weather can cause pond liners to crack or shift, leading to leaks. Carefully inspect the edges and liner for any visible damage. If you notice a drop in water level, try a bucket test to confirm a leak. Repair kits with self-adhesive patches are handy for fixing minor tears without draining the pond. Checking your pipes and fittings for any signs of wear or damage is also a good idea.

7. Add Aquatic Plants for a Balanced Ecosystem
Aquatic plants do more than beautify your pond—they help balance the ecosystem by absorbing excess nutrients. Choose a mix of oxygenating, marginal, and floating plants for the best results. Marginal plants like iris and pickerel weed enhance pond edges, while submerged plants boost oxygen levels and control algae. Planting in aquatic soil and baskets prevents soil from clouding your water.

8. Protect Your Fish from Predators
As wildlife becomes more active, so do predators like herons. Installing netting is an effective way to keep them at bay, but if you prefer a more natural look, consider floating plants and rock caves where fish can hide. Motion-activated deterrents and decoy predators can also help discourage unwelcome visitors.
