Introduction to the self-leveling functionality of the REEFER DC Skimmers

Protein skimmers perform 2 important functions. The primary function is
to mechanically remove dissolved organic matter (proteins / bacteria)
from the aquarium water. The secondary, but not less important function
is to oxygenate the water through vigorous mixing of the water with
a continual supply of fresh air. Both functions are responsible for
maintaining water quality which can be monitored by measuring the
REDOX or ORP of the water.
Skimmers remove proteins from the water as they stick to the surface
of air bubbles that ascend the neck of the skimmer as a foam, and
thereafter settle in the collection cup as a liquid. The reaction chamber
of the REEFER Skimmers was designed together with the range of PSK
pumps to provide the necessary flow rates of air and water in an optimal
ratio and contact time to optimize the protein removal for different
aquarium volumes. The wetness of the foam in the skimmer neck is
determined by adjusting the mechanical regulator of the skimmer that
restricts the water outlet of the reaction chamber.
Any change in water chemistry, in particular changes that can affect the
surface tension of the water will affect the delicate balance that enables
a stable foam production. Some chemicals can prevent foam from
forming while others can cause the air/water mixture to expand causing
an extremely wet foam to suddenly rise inside the skimmer neck and
flood the collection cup with clean seawater. This phenomenon, known
as over-skimming, typically occurs in a reef aquarium after feeding,
adding new livestock, reef-scaping, equipment maintenance, water
changes or changes in the waterborne bacteria population.

The self-leveling functionality of the Reefer DC-Skimmers combines the
variable intensity of the PSK DC-1200 skimmer pump with a dual input
sensor that monitors both the wetness of the foam in the skimmer neck
and the liquid level in the collection chamber of the cup, to optimize the
performance of the skimmers.
When the self-leveling function is enabled and wetter than normal
foam is detected in the skimmer neck, the intensity of the PSK-DC
skimmer pump is immediately reduced to prevent over-skimming and
then incrementally increased back to the set intensity maintaining the
maximum possible aeration without allowing over-skimming.
If a full cup situation is detected, the intensity of the PSK-DC skimmer
pump is reduced to maintain efficient oxygenation of the water inside
the skimmer reaction chamber, without pushing new waste to the cup,
until it is emptied and regular operation can be restored.
