The first time you fill the aquarium, it is
important to be sure that the system is not
overfilled.
To do this, first install all plumbing,
equipment, and place baffles as desired.
Fill the aquarium so that the water is just
beginning to spill into the sump. Then fill
the sump to a few centimetres from the top.
Turn all equipment on and wait for the
water level in the sump to stabilise - this
is the maximum running water level in the
current configuration.
Mark the water level with a marker pen and
use this as a reference for the future.

The drain of the ReefSys is designed to run silently by minimising turbulence in the drain pipes. When
running correctly, the main drain will work as a full siphon and no air will be drawn through. For it to run
correctly, the plumbing will need to be tuned using the gate valve to control the flow.

Wait a few minutes for the
water levels to stabilise, then
close the gate valve a little
(about a quarter turn) and
wait for at least ten minutes.
Repeat this procedure until the
water level in the weir is just below
the emergency drain. Once the
correct setting is found, it should
require little attention but may
need adjustment from time to time.
