Got a small tank? Today's Practical Fishkeeping advent calendar prize is ideal for you, whether it's a fresh or marine set-up.
Win a Fluval Nano ECO LED Light worth £64.99.
Suitable for both freshwater and marine set-ups, the ECO Nano is a scorcher of a light for the budding pico aquascaper, or micro-reefer.
Running at just 6.5W, and churning out 9000K, clean white light from a cluster of 14 diodes, the lens allows for a 120° spread, so you’ll not end up with a spotlight effect, laserbeam of light shooting straight down.
Hagen says the light features C.O.B. technology (meaning chip on board), which leads to heightened efficiency and output.
