Cyanobacteria Why blue-green algae can be a serious risk to people, pets, fish and water quality Cyanobacteria, often called blue-green algae, are much more than an unattractive surface bloom. In ponds, lakes and reservoirs, they can present serious health, ecological and legal concerns, especially during warm, still and nutrient-rich conditions. For landowners, lake managers, fisheries, golf courses, councils and private pond owners, cyanobacteria should never be ignored. A

When extreme heat arrives, most pond owners worry about the water getting too warm. But the biggest danger to pond fish is often not the heat itself. It is the sudden drop in oxygen that can happen when water temperatures rise. Warm, still water holds less dissolved oxygen than cooler water. At the same time, fish, bacteria, algae and decaying organic matter all place extra demand on the oxygen available in the pond. This is why a pond that looks fine one day can become a ser

How FishLife Pond Services helps reduce algae, cyanobacteria and nutrient problems in larger water bodies Algae and cyanobacteria blooms are often a sign that a pond or lake has too much available phosphate in the water. Phosphate is one of the main nutrients that feeds algae growth. When levels are too high, water can become green, murky or covered in blooms. In larger ponds and lakes, this can affect oxygen levels, fish health, plant growth and the overall balance of the ec

Most pond problems don’t happen overnight. They build up slowly, often caused by well-intended actions that unintentionally disrupt the natural balance of the water. At FishLife Pond Services, we’re regularly called out to ponds that have been lovingly cared for, yet are struggling with poor water quality, algae, odours, or stressed fish and wildlife. In almost every case, the cause can be traced back to a handful of common mistakes. The good news? Once you understand what to

Freezing weather can be one of the most stressful times for a pond. Ice, snow, and prolonged cold temperatures don’t just affect the surface; they can quietly destabilise water chemistry, reduce oxygen levels, and put fish and wildlife at risk. Understanding what happens beneath the ice and how to respond correctly is key to keeping your pond healthy throughout winter and ready for spring. Why Freezing Weather Is a Risk for Ponds When temperatures drop, ponds undergo several
