Why Lake Mary needs algae

Corporate-park and HOA stormwater lakes across Lake Mary need scheduled mechanical maintenance.

Algae on Lake Mary water

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.

How we handle Lake Mary jobs

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

Algae in Lake Mary — FAQs

Do you serve Lake Mary for algae?+

Yes. Algae & Water Quality Management is one of our most-requested services in Lake Mary and surrounding Seminole County water bodies. We respond within 24 hours and schedule on-site inspections within 5–7 business days of contact.

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.
