From micro-soldering delicate circuitry and inserting magnets to executing the high-precision 3-step resin potting process, see exactly how these top-tier aquarium Auto Top-Off (ATO) systems are built. Watch as we put our hand-soldered unit through Tunze’s rigorous optical sensor and safety testing—and discover if it actually works or gets sent straight to the trash bin!
