How to separate high-density and low-density aerators in a simple way?

When using microporous aerators, some users do not understand their high density and low density! According to the feedback from users, let me tell you that the main difference between high density and low density is the surface layer of the aerator, which can be distinguished by the smoothness of the surface layer! Generally, high-density aerators are relatively smooth, while low-density ones are relatively rough.

Because the high-density openings are smaller, there won't be too many pores on the surface! Generally, there are about 1000-1200 air vents on a one-meter pipe, and the details of the openings may be different due to different manufacturers!

The above is one of the more effective identification methods, which is very practical!

General customers often distinguish the aerator by high and low density, and some users distinguish by the size of the bubble. The microporous aerator is actually the same in principle, corresponding to the high and low density!

 
High density = small bubbles; low density = large bubbles

Do you have a basic understanding of microporous aerators! In the practical application of aquaculture, users can choose flexibly according to their own needs, and can make aeration trays by themselves.
