❄️ Pond Top Tip: Dealing with Ice ❄️

If your pond ices over briefly — just a few hours in the morning — there’s no need to worry. Let nature take its course.

If the ice persists all day, create a small hole to allow air exchange:
- Pour a saucepan of hot water gently onto the ice.
- Or, float a ball on the pond before it freezes; remove it after ice forms to leave an air hole.

⚠️ Never smash the ice! Fish have very sensitive hearing, and sudden loud noises can cause unnecessary stress.

As winter temperatures drop ❄️, you might notice your pond fish developing waxy, jelly-like lesions on their skin. In most cases, this is a harmless viral condition known as carp pox 🐟

Carp pox often reappears when a fish’s immune system slows down in colder weather, but the good news is that healthy fish usually clear it naturally once the water warms up 🌤️

How are your fish looking this winter? 👀🐠

❄️ Pond Top Tip: Preparing for Winter ❄️

Winter is almost here, and your pond is entering its period of hibernation. During this time, fish become almost motionless in the colder water — but it’s still important to check water quality regularly. Stable, healthy water now will help your fish thrive come spring.

💧 What to check:
- Test for phosphate and nitrate — low levels are important, as excessive levels can lead to algae problems next season.
- Ensure ammonia and nitrite levels are undetectable.
- A partial water change if needed at this time of year, and always dechlorinate incoming tap water.
🧪 How often do you test your pond water? Share your routine in the comments and let’s help each other keep ponds healthy all winter!

🎄 Pond Top Tip 🎄

With Christmas just around the corner, it’s the perfect time to start planning for next year’s pond season — or even add a few pond care essentials to your wish list! 📝🎁

💧 Think about filtration: Technology has advanced a lot, so it might be time to upgrade. Remember, your fish may have grown or even bred this year — meaning your current filter system could be working overtime.

🎁 Gift ideas for pond keepers: From water testing kits (always handy!) to maintenance tools and replacement parts, there are plenty of practical presents to make pond care easier and more enjoyable.

🎄 Thinking about getting goldfish for the kids this Christmas? 🎁

Before you decide, here’s why tropical fish might be the better choice — and why a little research goes a long way when it comes to caring for fish responsibly. 🧐

🦈 You could keep a shark! (Well… a Red-tailed Black Shark! Not really a shark, but the kids like to think so!) They’re peaceful and live happily with barbs, danios, rainbowfish, and tetras.
🌈 More colour and variety — tropical fish come in many species that can live together, creating a lively, colourful aquarium.
🏠 Small and manageable — unlike goldfish, which grow quite large and need bigger tanks over time.
💧 More fish, same space — you can safely keep several small tropical fish in the same tank size that would only suit a couple of goldfish.
🐟 A greater range of behaviour to watch - from colourful guppies cruising at the surface to busy catfish cleaning the gravel. What about an upside-down catfish, or a glassfish - that you can see right through?

✨ A tropical aquarium is a fun, educational way for children to learn about caring for pets — but it’s always important to research the responsibility involved to make sure it’s the right choice for your family.
