The most common hard tubes are clear and transparent. In addition, hard tubes made of brass and carbon have also gained popularity. Now, Alphacool offers the Ice Tube as part of its Ice product line. The surface visually resembles ice and feels like it too—somewhat rough, yet still smooth. The Ice Tube significantly alters the appearance within the system. Especially after filling the system, the actual effect is best observed. The water has the look of frozen ice. When the loop is illuminated with LEDs, clear hard tubes reflect the individual LEDs very well, but this is not the case with the Ice Tubes. Here, the light is diffused, resulting in a much softer and better illumination. The Ice Tube can be bent like all acrylic hard tubes using the appropriate bending tools. However, this noticeably changes the appearance of the Ice Tubes at the bends, no longer matching the original look. This can create an additional effect, but those who wish to maintain the Ice Tube appearance should use appropriate fittings for bends.
