Reef Primer 45 g — Gentle Anti-Pest Coral Dip for Corals & Frags - Polyplab

Polyplab Reef Primer 45 g — the dip that cleans your corals before they go in

Polyplab Reef Primer is a potassium-salt dipping solution that clears corals and frags of pests and hitchhikers before they enter your main tank. It slots into your acclimation routine: a quick pass through the solution and the coral goes in clean.

ReefSolution's take

It's probably the most reliable all-purpose dip we use: remarkably gentle on corals — they barely react — yet brutal on pests and hitchhikers. Polyplab backs this up: the formula won't trigger a stress response during the dip. For us, it's a must in every new-coral acclimation.
