- Thousands of very fine bubbles are
diffused and
remained in the pond water as they are all small.
When
bubbles come up to the water surface, they
also bring dirty materials
up.
- Diffusing operation create strong aeration and
also
quickly stir the water from the bottom to the

4
units of 1HP paddlewheel aerator +
2 units of 1HP (1HP/60HZ,
1.5HP/50HZ) diffuser.
while the stocking density is 50 pcs /
M3.
- The
diffusing disk may touch down the pond bottom
in case the water is
lower than 20 cm. Turn off the
