Polyp Lab Primer One Shot (Single Pouch)

PolypLab Reef Primer One Shot is a premium coral-dip powder designed to clean and protect new coral frags or live rock before introducing them into your display tank. The dip removes parasites, flatworms, harmful nudibranchs, unwanted algae, bacterial infections and other hitchhikers — all without stressing the coral if used exactly as directed. 

To use, dissolve one 9 g pouch in ~4 L of aquarium-water, stir until fully dissolved, then submerge coral/frags for up to 5 minutes while gently agitating the water. Rinse (optional), then place corals directly into your reef — do not add the solution to the tank itself.
