Swell Air Can

Swell Air Cans are solid reliable airstones that are weighted and supply air to the water when connected to an air pump.

Air stones are a must for koi ponds and quarantine tanks, where the good bacteria in your filter needs plenty of oxygen to combat the bad. In larger ponds with lots of fish, waste can be a problem, so ensuring a good supply of oxygen to aid biological filtration, good water conditions and of course good fish health is vital.

Our own brand air stones are designed to be used with an air pump and airline (not included).

• These high quality and long life air stones are made from a refined ceramic compound.
• They produce very fine aeration and can be used in conjunction with any good air pump.
• To fit silicone airline: 4-6mm.
