Price: ₹170.00 · In stock

A 30 cm flexible air stone. KW Zone’s size sheet lists it as model BSF-30. The blister is a black porous tube with one barbed inlet and a closed end, so the bubbles come out along the tube rather than from a single stone. The tube bends, including into a curve. A Finnish AIM listing says it fits a standard 4/6 mm airline and can sit under the sand. The same listing says a clogged tube can be soaked in hot water for about eight minutes and then brushed. An air pump and airline are not in the blister. The card prints every length from 20 cm to 120 cm. The 30 cm length is the BSF-30 row on the manufacturer sheet, not a tick that is readable on this photo.
