UP Aqua A618B/C Black & Clear Silicone Air Tube (Per Metre)

Sold per metre, the A618B black and A618C clear silicone air tubes let Singapore hobbyists pick tubing to suit the look of the tank. Clear line all but disappears in open water, while black hides neatly against a dark background or behind a rimless tank. Both share the standard 4/6mm bore, so they work with common air pumps, sponge filters and pressurised CO2 setups without adapters.

Silicone tubing handles our humid, warm rooms well, staying flexible rather than cracking like older PVC lines. Buying just the length you need keeps cost down for a single nano or shrimp tank. We recommend installing a check valve on every line so water cannot back-siphon into a pump or regulator sitting below the tank, which is a real risk during the monsoon-season outages we get in Singapore.
