Is the difference between nano-disks and gas stones bubble density?

With the same power of air pump, the gas output of gas stone is several times that of nano-gas disk. However, nano-gas is superior in beauty and bubble size, but nano-gas is also easy to block bubbles and it is not easy to clean fine bubbles and coarse bubbles.

The difference between the gas stone and the gas disk of the oxygen-increasing pump is mainly reflected in the shape. The gas disk is relatively large, the whole is relatively round, and the gas stone is relatively small, occupying less space. The two functions are similar, but for large fish tanks, it is better to use air trays.
