Compatibility

What it is. The Fluval Marine 3.0 Bluetooth LED is Fluval’s saltwater-tuned reef light, sized here for aquariums of 36–48″ / 91–122 cm — the exact range on Fluval’s own listing for this 46W model.

Where this sits in the Fluval range. Marine 3.0 is the saltwater sibling to Plant 3.0 (the freshwater/planted version) and sits above the compact Marine 3.0 Nano; all three share the same FluvalSmart App control and H.T.E. LED platform, with case size and LED band count the things that change between them.

Setup & Use

App control. Operated exclusively via the free FluvalSmart App over Bluetooth — there’s no on-unit dial or remote, so a phone or tablet with the app installed is required to run the light day to day.

Spectrum. Fluval’s own spec for this line: 7 unique LED band waves with independent colour control, aimed at supporting coral colouration and growth rather than plant photosynthesis specifically.

Daily cycle. A programmable 24-hour light cycle runs a gradual sunrise, midday peak, sunset and night phase automatically once set, rather than a hard on/off.

Build. A fully encased aluminium shell carries an IP67 waterproof rating, and each individual LED casts 120° of spread for even coverage without dead spots across the fixture’s width.
