Compatibility

What it is. The Fluval Marine 3.0 Nano Bluetooth LED is the compact member of the Marine 3.0 saltwater lighting line, built at 20W for nano and desktop reef tanks rather than the full-size aquariums the 22–46W Marine 3.0 fixtures cover.

What’s different from the full-size Marine 3.0. The product’s own listed features call out a new over-the-glass mounting design in place of the full-size unit’s fixed legs, a fully adjustable head (up/down, side-to-side, forward/backward), and a frame Fluval states is 23% lighter than the previous generation — all changes aimed at desktop and nano setups where a leg-mounted fixture doesn’t fit.

Setup & Use

App control. Operated via the free FluvalSmart App over Bluetooth, the same control platform as the rest of the Marine 3.0 and Plant 3.0 range — a phone or tablet with the app is required to run and program the light.

Positioning. Because it mounts over the glass rather than clipping to it, the fixture can be repositioned in any direction without moving the tank’s rim clips, which is what the “fully adjustable positioning” feature above refers to.

Waterproofing. An IP67 rating and fully encased aluminium shell mean the fixture tolerates splashing and humidity at the water’s surface without issue, consistent with the rest of the 3.0 range.
