Is Your Pond Ready for the Big Heat?

Koi Ponds · Lakes · Water Features

Sydney is forecast for one of its hottest summers on record. Whether you look after a backyard koi pond or a public lake, the chemistry is the same — and so is the failure chain: heat drives algae, algae crashes oxygen, oxygen kills fish and closes waterways. Spend a day with five specialists and leave with a plan you can act on before it happens.

Sunday 18 October 2026 10:00 AM – 3:30 PM South-West Sydney

Held at a private koi farm in Sydney’s south-west. The exact address is sent with your booking confirmation.

Algae bloom on a drying pond during an El Niño summer
Who it’s for

A hot summer is coming. Is your pond ready?

A strong El Niño is approaching and record temperatures are already here. This summer will bring real pond challenges – but the right proactive measures now can save you stress, fish losses and expensive fixes later.

The physics don’t care whether your water body is 2,000 litres or 2 megalitres: as temperature rises, dissolved oxygen falls, algae accelerates and the nitrogen cycle strains. What changes is the consequence – a dead koi, a resident complaint, a closed lake, or a failed irrigation supply.

  • Understand why heat triggers algae blooms — and why most of what you read about algae misses the point
  • Learn how to keep dissolved oxygen stable in warm water
  • Read the early warning signs before a pond tips out of balance
  • See live demonstrations, and have your own water sample tested and discussed
  • Review this season’s equipment and treatment options — what earns its place, what doesn’t

Personal access: Michael and the presenters stay on after the formal programme for one-on-one conversations about your own water. It is the kind of access normally reserved for a private site visit.

What’s included

  • Full-day programme with five specialist presenters
  • Your own water sample tested and discussed on the day
  • Morning tea and a catered lunch, dietary requirements on request
  • Welcome pack and lucky door draw on arrival
  • One-on-one time with the presenters after the programme

What’s at stake for you

Same water chemistry, very different consequences

🐟Pond & koi owners

Overnight fish loss in a heatwave — warm water holds less oxygen.

🏢Strata & facility managers

Legionella risk and WHS duty of care — plus the top source of resident complaints.

🏞️Council parks & stormwater

Blue-green algae means a public health advisory, a closure and a media story.

Golf, schools & aged care

Irrigation fails at peak demand; a visible bloom raises duty-of-care questions.

🚜Aquaculture & production ponds

Losses counted in stock, not complaints — and weeks to recover.

📐Landscape architects & consultants

Design it in at the start — circulation, depth, shading — or retrofit in February.

If you are responsible for water that people look at, stock, swim near or rely on — this day is for you.

Bring a sample of your water. A 500 ml jar, or photos on your phone — we test and talk through real water on the day.

Your Speakers

Five specialists, one practical game plan for extreme heat

Michael Regnis

Michael Regnis

Troubleshooter, System Designer & Pond Rectifier — Fishcare

Michael has spent 45 years designing, troubleshooting and rectifying ponds and water features across greater Sydney — a problem-solver who keeps going until he finds the answer.

Here he is joined by four specialists — a biotech founder, a retail expert, a koi breeder and an environmental scientist — for one practical game plan for extreme heat.

He stays on afterwards for as long as needed to talk through your own water.

Dr Matthew Pang

Founder & Director, BBA PurePond / BBA Biosolution Australia

PhD (University of Sydney), and founder of a biotechnology company working on beneficial bacteria for water and soil. Matthew supplies aquaculture farms, pond professionals and wastewater projects across Australia, and will share how the nitrogen cycle drives stable water and healthier koi.

Paul Talbot

Owner, Majestic Aquariums, Taren Point

Owner of Sydney’s largest aquarium store, and brother of award-winning importer Chris Talbot. Paul brings the retail and equipment view — Dainichi food, Aquael pumps, Seachem treatments — and what is genuinely worth the money.

Ginny Lin

Environmental Scientist & Engineer

Degrees in environmental engineering, science and management — China, Australia, the United States — and more than ten years restoring rivers, wetlands and catchments in the field. She reads a backyard pond and a council lake with the same framework: what to measure, what the numbers mean, and when a bloom is cosmetic versus a public-health event.

Ralf Bohner

Owner / Operator, AusKoi

An experienced koi keeper and breeder, and your host on the day. Ralf will be available throughout the event to answer koi-specific questions – from selection and handling to breeding and health.

Ginny Lin — dissolved oxygen, temperature, pH, ammonia and nitrate: what to measure, what the readings mean, and when a bloom is cosmetic versus a public-health event.

12:00 PM

The nitrogen cycle and beneficial bacteria
