Identify what you actually have
The three things people call "algae" respond to completely different treatments, so identification comes before any product goes in the water.
- Planktonic algae — suspended bloom, pea-soup green water, no strings
- Filamentous algae — stringy or hair-like mats you can pick up on a stick
- Cyanobacteria (blue-green) — paint-like scum or streaks; can be toxic to pets and livestock
- Duckweed and watermeal — tiny floating plants, not algae, and treated differently
Treating without killing the fish
A full-pond kill on a heavy bloom is the most common way homeowners lose their fish. Dying algae consumes oxygen as it decomposes, and on a hot, still night that alone can crash a pond. We treat in sections with days between, apply at labeled rates, and run aeration through treatment so oxygen never bottoms out.
Licensed aquatic treatment
Product choice follows the species and the pond's use. If you swim, water livestock or irrigate from the pond, we tell you any re-entry or use interval up front, before we spray.
Mechanical removal
For heavy mats, pulling the biomass out with the weed boat removes the nutrients with it instead of leaving them to decay and feed the next bloom. On a badly overgrown pond this beats chemistry every time.
Fixing why it keeps coming back
Algae needs nutrients, sunlight and warm shallow water. Address those and blooms get smaller and later every year instead of bigger.
- Aeration to circulate the water column and stop stratification
- Cut the nutrient inflow: fertilizer, grass clippings, livestock access, septic and runoff
- A vegetated buffer strip on the bank to intercept runoff before it reaches the water
- Restore depth where muck has filled the pond in — shallow water is warm water
- Beneficial bacteria and, where suitable, pond dye to limit light
A realistic schedule
Most Gulf Coast ponds want eyes on them monthly or quarterly from spring through early fall. Catching a bloom small is a single visit; catching it in August at full coverage is a project, and a riskier one for the fish.
When to call us
If the bloom is thick enough that you cannot see a foot down, if it looks like spilled paint, or if it comes back every year no matter what you buy, that is a management problem rather than a product problem.
