NF KS-QHL-25 Rubber Air Diffuser Round (25cm – D16)

The NF KS-QHL-25 Rubber Air Diffuser for SG Tanks and Ponds

This 25cm round rubber air diffuser, sized for D16 tubing, is a flexible disc that spreads a wide ring of fine bubbles from a single point. We sell it to keepers who want broad, even aeration across a larger footprint, whether that’s the base of a tall display tank or a corner of an outdoor pond. The soft rubber membrane flexes as air passes through, which helps shed mineral build-up and keeps bubble output consistent longer than some rigid stones.

In Singapore’s warm 27-29C water, dissolved oxygen sits lower than in cooler climates, so generous aeration is cheap insurance for a busy community tank or a stocked pond on a hot afternoon. The fine bubbles also drive surface movement and gentle circulation, which discourages the stagnant film that can form in still water during our humid, low-wind days.

Pair it with a correctly sized pump from our air systems range. Our oxygenation guide and the air pump guide walk you through matching pump output to diffuser size.
