Evolution Aqua have introduced an innovative range of self sinking air line for connecting air pumps and air stones, available in 4mm, 8mm and 10mm sizes.
This new sinking air line simply drops to the bottom of the pond without the need for additional weights. The black air line is designed to be completely discreet whilst making for a tidy installation at the base of the pond. Made from a PVC based compound, the air line has a high resistance to UV light and resists kinking and cracking.
Evolution Aqua Air Line fits most pond and aquarium air pumps.
