Features:
【PACKAGE CONTENT】You will receive 1pc x 50mm bubble stone, and it is suitable for 20-80cm/7.87-31.5inch fish tank. Please pay attention to whether the size is suitable before purchasing. Suitable for home and office.
【ULTRA HIGH OXYGEN】The bubbles released by this aquarium air stone are smaller, denser and more uniform, which greatly increases the oxygen dissolution rate in the water, reduces carbon dioxide, and allows your fish tank to have sufficient oxygen.
【UNTRA QUIET】The operation noise in the water is very small, which does not affect the normal activities of aquatic organisms and does not affect the sleep of children. The surface of the disc is made of smooth plastic, which is gentle to fish and does no harm.
【MANUAL ADJUSTABLE】This aquarium air stone produces a large number of tiny bubbles, resulting in a charming view. When the power of the air pump is sufficient, the best effect can be achieved by adjusting the air output of the air pump.
【EASY MAINTENANCE】Clean the stone once a month to prevent clogging. Just soak it in water, gently brush its surface, and then dry naturally in a cool and ventilated place. Soak in the aquarium for two hours before use for best results.
