A Nursery Lake Choked with Azolla, Duckweed and Blue-Green Algae
At Avalon Nursery in Ballarat, Victoria, an irrigation dam had become completely smothered by azolla, duckweed, and blue-green algae. The thick, mat-like growth made it almost impossible to tell where the water began.
The situation turned serious when a customer’s young child accidentally walked straight into the dam, mistaking the dense layer of azolla for a patch of muddy ground. Fortunately, no one was hurt—but for the nursery, it was the final straw. They needed to fix the problem quickly and permanently.
With no mains power available near the dam, running traditional electric aeration wasn’t an option. The client needed a reliable, solar-powered system that could restore circulation and oxygenation fast—without relying on chemicals or ongoing power costs.
That’s when Ultimate Pumps & Irrigation, one of our regional resellers, contacted us for expert guidance on selecting the right aeration system for the job.
