water management system
Surface Skimmer / Overflow Box
Surface water from the aquarium flows via the removable comb sections
of the surface skimmer into the overflow box that houses the dual
intakes of the silent-flow downpipe system and the outlet nozzle of
the sump return pump. The silent-flow downpipe system includes a
flow-regulated main downpipe and a secondary overflow bypass pipe.
An external pipe with a clear upper section is placed over the main
downpipe to ensure positive water motion throughout the entire height
of the overflow box.
The fine adjustment flow valve on the main downpipe enables the water
level in the overflow box to be maintained at a constant height between
the intakes of the main and bypass pipes, which ensures positive surface
skimming while eliminating all noise from the water flow to the sump.
An incorrect setting of the flow valve will be accompanied by the sound
of the water returning to the sump and is an indication that the flow
valve needs adjusting.
Sump /ATO
Water from the flow-regulated main downpipe and the secondary
overflow bypass pipe enter a compact reception chamber in the sump.
Care should be taken in the choice of any filter media placed in the
reception chamber as the turbulent flow conditions from the downpipe
could cause a constant discharge of fine media particles.
The water then flows through the 400 micron filter before entering the
constant-height main reactor or skimmer chamber. If the filter bags are not
cleaned frequently enough and become blocked, the water will bypass the
filter bags without affecting the overall operation of the sump.
A bubble trap labyrinth with coarse foam separates the reactor chamber
from the pump compartment to prevent bubbles from the skimmer being
returned to the aquarium.
Any loss of water due to evaporation will cause a drop in the water level
in the pump compartment of the sump which will be compensated by
the ATO system.
Maintaining a constant water height in the pump compartment (with the
ATO) is essential for the stability of the entire water management system
by ensuring a constant head pressure on the intake of the main pump.
The reservoir contains water for approximately 3 days of evaporation and
should be kept topped up at all times.
Return Pump
The recommended flow rates for the return pumps are as shown in the
table below. The use of higher rated pumps will result in a higher water
level in the aquarium unless an appropriate modification is made to the
surface skimmer combs.
