Frequently Asked Questions
Q: What size air pump tube does this aquarium air stone require?
A: This 4cm air stone disc is designed to fit a standard soft air tube with a 4mm inner diameter — the most common size used with aquarium air pumps. Simply push the tube connector into your pump line for a secure fit.
Q: Do I need to prepare the air stone before using it in my fish tank?
A: Yes — we recommend soaking the air stone in clean water for approximately 15 minutes before first use. This saturates the mineral stone and ensures optimal, even bubble production from the start.
Q: Can this air stone be used in a hydroponic system or garden pond?
A: Absolutely! While it is ideal for fish tanks and aquariums, this sintered mineral air stone works equally well in hydroponic reservoirs and outdoor garden ponds to maintain healthy oxygen levels in the water.
Q: Is this air stone washable and reusable?
A: Yes. Unlike basic air stones, this one is high-temperature sintered for durability. It can be rinsed and reused multiple times. If bubble output reduces over time, soak it in clean water or gently rinse it to restore performance.
