Classification: CPC A  Y | IPC A

Claim 0:
1. A composition for mitigating, inhibiting, and/or eliminating phytoplankton growth in a waterbody, the composition consists of a plurality of coated granules; each of the coated granules comprises:
an algaecide at a concentration of 80.0-99.5% (w/w) of the composition, wherein the algaecide is selected from a copper based algaecide, an aluminum based algaecide, or any combination thereof; and
a hydrophobic water insoluble coating material coating the algicide and being present at a concentration of 0.5-20% (w/w) of the composition, wherein the coating material is selected from a saturated or unsaturated fatty acid, a triglyceride, or any combination thereof;
said copper based algaecide is Copper(II) sulfate;
said aluminum based algaecide is Aluminium sulfate;

wherein the critical surface tension of the composition is between 15-60 dyn/cm, the melting temperature of the composition is 50-90° C., and an acid value of the composition is 3-8 mg KOH per gram; and wherein the relative density of the composition, prior to being submerged in water, is above 1.0 g/cm3 such that the composition initially sinks after being applied, and wherein the composition becomes floating 0.25-60 minutes after being submerged in water, thereby causing a surfacing of the composition.
