Which tanks is it best for?
The T4-30 suits nano and small tanks as decorative accent or back-lighting. It is for visual effect rather than plant growth — for live plants choose a full-spectrum planted light such as the Sobo AL-180. For a longer 37 cm version see the Blue pet T4-40. See our aquarium light guide.
How to use it
Position the tube along the back or base of the tank and run it 6–8 hours a day, ideally on a timer, with a dark night period. Keep the adaptor above water and route the cable with a drip loop. Avoid leaving it on continuously to limit algae. See should you turn aquarium lights off at night.
