Featuring dual precision optical sensors, a quiet 74 GPH micro pump, and advanced QST 2.0 safety tech, it ensures stable water levels and protects your aquatic life from evaporation stress. Compact and easy to install with included accessories, it’s the ultimate smart solution for busy aquarium enthusiasts seeking reliable, hands-free maintenance. ## Description Evaporation is every tank owner’s constant enemy. Auto top off systems are a crucial piece of any fish tank. FZONE Automatic Top-Off (ATO) systems provide convenient assurances. The products use water from a reservoir to refill tank or sump levels. This helps maintain specific gravity and salinity. In particular, this is important in reef and marine tanks. Drops in these levels increase stress on fish and can be fatal. Review: Veramente un ottimo prodotto, la schiena ringrazia!!! - Avendo in casa diverse vasche nel periodo estivo mi trovo a dover rabboccare l'acqua evaporata, se la vasca è piccola ci si sta dietro ma quando questa è grande diventa un vero problema. Per tale scopo ho acquistato questo sistema di rabbocco automatico, l'ho testato appena arrivato simulando una evaporazione minima e devo dire che dopo che l'acqua è scesa di pochi millimetri, il sistema ha attivato la pompa per ristabilire il corretto livello, ho ripetuto diverse volte questa prova e il sensore è sempre intervenuto in modo preciso. La pompa l'ho immersa in una tanica da 20 litri essendo piccola per mia fortuna è passata dal foro del tappo, la pompa riesce a spingere l'acqua tranquillamente nella vasca nonostante sia a livello pavimento. Nella confezione c'è tutto il necessario all'installazione, non manca proprio nulla, quindi che dire il prodotto è perfetto, completo e allo stesso tempo funziona bene. Dimenticavo lo utilizzo anche per i cambi settimanali d'acqua così non porto più su le taniche e fa tutto lui in automatico e la mia schiena ringrazia.
