ATI T5 Blue Plus Fluorescent Tube

ATI Blue Plus is designed to enhance fluorescent pigments, deepen blue coloration and balance yellow or washed-out aquarium lighting. Its broad, linear light source provides even coverage and helps reduce shadows created by point-source LEDs.

The tube is suitable for SPS, LPS, zoanthid and mixed-reef aquariums. It may be combined with ATI Coral Plus, Aquablue Special, Purple Plus or True Actinic tubes to create the preferred colour balance.
