UP Aqua A-617C / A-618-B Air Tube on 100M Rolls

These 100M air-line rolls are aimed at Singapore breeders, shops and serious hobbyists who run multiple tanks and get through tubing fast. The standard 4/6mm bore fits common air pumps and CO2 equipment, so one roll covers sponge filters, air stones and diffuser feeds across a rack. Buying a full roll works out cheaper per metre than short cuts when you are plumbing a whole fish room.

In our climate, silicone-type air line stays flexible and resists the hardening you sometimes see with cheaper PVC tubing left in a warm room. We still recommend a check valve on each line, both to protect CO2 regulators and to guard pumps mounted below tank level during a monsoon power cut. Trim ends cleanly and warm a stiff tube briefly to ease it over barbs without splitting.
