Aquarium Tubing

Aquarium tubing made of silicone/rubber material is easy to work with. Tinted blue-green by the manufacturer, it blends in nicely, virtually disappearing under water. Rubber tubing can be bent around decorations without kinking and does not crack with age. To slide tubing easily onto the pump outlet or the stem of an airstone, hold it briefly under very hot tap water to soften it slightly. It returns to normal when it cools.
