Filamentous algae in Florida ponds: why it keeps coming back
If your pond is clear in March and a green-mat disaster by June, the problem isn't the algae — it's the nutrient load.

Algae & Water Quality Management across Central Florida
Filamentous algae and pond water quality management for Florida residential and HOA waterways.
Typical price range
$800–$4,000
Per-visit treatment cost. Aeration installations run $3,500–$12,000 one-time. Buffer plantings $8–$15 per linear foot.
What is algae and why it matters
Algae blooms are the symptom — nutrient loading is the disease. We treat algae blooms with targeted intervention but always pair it with the upstream fix: shoreline buffer plantings, aeration, and runoff source management. Without addressing the nutrient supply, every algae treatment is temporary.
Cyanobacteria blooms are the leading cause of dog deaths near Florida ponds and a growing public health concern. HOA pond aesthetics are also among the top homeowner complaints in master-planned communities.
Signs you need algae service
!Green surface scum or mats
!Bright green or blue-green water column
!Foul smell, especially after still days
!Dogs reluctant to drink or sick after exposure
!Fish gulping air at the surface
The problem
Why DIY and herbicide-only fail
Florida's warm waters and nutrient-rich runoff create ideal conditions for filamentous algae mats and cyanobacteria blooms. Surface scum kills aesthetics, depletes oxygen, and in cyanobacteria cases produces toxins harmful to dogs and humans. HOA ponds with mowed turf to the water's edge are the worst-case nutrient-loading scenario.
Our approach
How we handle it
Targeted algaecide on active blooms when needed, mechanical mat removal for filamentous accumulations, then a structural intervention plan: 6 ft native shoreline buffer, aeration if depth allows, and homeowner education on fertilizer setbacks. Recurring water testing tracks nutrient levels.
- ✓Water testing for nitrogen, phosphorus, dissolved oxygen
- ✓Targeted treatment of active blooms
- ✓Shoreline buffer planting plans
- ✓Aeration system design and install
- ✓Cyanobacteria identification + alert protocol

FAQs
Algae & Water Quality Management — frequently asked questions
Why does my pond keep getting algae?+
Nutrient loading. The most common sources are mowed turf to the water's edge, fertilizer runoff, dog waste, and stormwater inflow from upland sources. Until those inputs are addressed, every algae treatment is short-term.
Is the green stuff in my pond toxic?+
Filamentous algae mats are not toxic to humans or pets. Cyanobacteria (blue-green algae) blooms can produce toxins that are dangerous to dogs and harmful to humans. We can identify which one you're dealing with from a sample.
Will copper sulfate kill my fish?+
Copper sulfate is widely used and generally fish-safe at label rates, but it suppresses dissolved oxygen as the algae decays. We dose conservatively and recommend aeration during treatment on stocked ponds.
Do I need an aerator?+
Aeration helps any pond deeper than 6 ft and is essential on stocked fishing ponds. It does not replace nutrient management but prevents the worst summer dissolved-oxygen crashes.
