Review on 💧 XSPC EC6 Blue Opaque Water Cooling Coolant - 1000ml Premix by Robert Howell

Nice light blue opaque or pastel blue, turn on the UV lamp and it starts to glow. It tarnishes over time, but what I like about this coolant is that it doesn't build up on my parts. Becomes a pastel and opaque brand. If you really want your coolant to pop, take a 15ml bottle of blue UV dye and add a few drops if the color doesn't glow that much under UV light.
