● Product Description

This is a set of 50 high-quality Bubble Diffusers (Air Stones) widely used by aquarium enthusiasts and professional aquaculture sites.

Unparalleled diffusion and filtration! Fine, uniform bubbles dissolve into the water, maximizing oxygen supply efficiency.

When you feel the bubbles are getting weak or the stone is getting dirty, you can replace it immediately with plenty of spares! With 50 pieces, you can use them freely in various situations, whether you have multiple aquariums, large filtration tanks, outdoor breeding of killifish, or even aquaponics on your balcony.

● How to Use/Install

Before use, soak the main unit in aquarium water for about 15-30 minutes to allow it to acclimate.

Firmly insert the air tube (sold separately) into the connection part of the stone.

Turn on the air pump and adjust so that the bubbles come out evenly.

* When using for the first time, the bubbles may be uneven, but they will come out beautifully from the entire surface once they acclimate to the water.
* If clogged, you can repeatedly use it cleanly by lightly scrubbing the surface with a brush or washing it with a diluted cleaning solution.
