First measurable change in 7-14 days. Phytoplankton populations grow 21-54% per day under typical pond conditions and visibly out-compete toxic algae within two weeks of inoculation. Full stabilization continues across the warm season.

Yes. The phytoplankton acts as a biostimulant when irrigated, returning phosphate and nitrate to plant-available form. Safe for golfers, livestock, fish, and people. No NPDES permit required.

Copper destroys algae cells but leaves the phosphate, nitrate, and ammonia that fueled the bloom — guaranteeing the bloom returns. Copper also accumulates in pond sediment, sterilizes the bottom, and re-circulates onto turf or fields when you irrigate. Hydralife removes the nutrient source itself by out-competing the algae, then becomes a soil biostimulant on irrigation.

For most ponds we ship 100 gallons of concentrated live phytoplankton in a 5-gallon bucket. Larger or chronically blooming ponds may need a mid-summer follow-up. Contact us with pond size and water source for a specific protocol.

Yes. We conduct free N and P testing on samples customers ship back to us so you can verify the phytoplankton is consuming nutrients as designed. No extra cost.

No. Pour into the pond and continue normal operations. No course closures, no field closures, no livestock exclusion period.
