dc.description.abstract	The invention relates to the protocol for harvesting of microalgae, Chaetoceros calcitrans by manipulation of electrolytic flocculator settings. The harvesting system comprised of a holding tank for the microalgae, a DC power supply with variable voltage selector, ammeter and voltmeter. The best settings of 6/6 units Al/Pb probes with voltage selector set at point 1 to supply 3 volts to complete the electrolytic cell. The Pb in the paste was reduced by 97% with values of 34.27 ± 0.39 ppm with 0 - 0.24 ppm Pb in the effluent discharge. The Pb content in secondary live food, Artemia salina was further reduced by 78% based on feeding trials with 7.8 ± 5.1 ppm Pb content. This system will be beneficial to hatcheries for use onsite due to its simplicity and affordability.	en
