PRECAUTION : (for
the first time operation )
- 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
surface.
- During the short period of dirty materials
decomposition and
precipitation, fish and shrimp
may get stressed although the environment
is
improving, stop feeding is required in this period
of time.
- No need to use too many unit of cyclonic aerator in a
pond.
The recommended standard number of
aerator in a one-hectare pond
is as follow:
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
aerator before the water
