What is filamentous algae?


Algae is common in the cool months

Filamentous algae grow on the bottom. Its common name is angel hair algae. When holding a handful, it resembles wet hair.  The color is lime green.  The amount present is determined by nutrient levels in the water.  Nutrients enter ponds from rain runoff across fertilized lawns or agriculture fields.  Another source is waste from fish regularly fed floating food.  When a growing cycle is complete, gases accumulate beneath patches of old growth and separate it from the bottom. Detached matter floats to the surface and drifts around with prevailing winds.

Why should I stock tilapia?

Algae can be controlled with chemicals, but maintenance must be done with each new cycle. Tilapia offer sustained, biological management without chemicals.  They consume new growth on the bottom and prevent unsightly mats from reaching the surface.  Tilapia also supplement the pond’s food chain.  They reproduce every 21 to 25 days and contribute valuable forage for sport fish, especially bass.
