7. Ensure that the inlet and outlet pipes are securely attached
to the chiller. Plug in the chiller pump and check that the
water is circulating through the chiller without leaks at any
of the connections in the piping.
8. Pay attention to the drop in water level and refill the tank
with freshly mixed salt water at the same salinity, pH & temp.
9. Operate the chiller according to the instructions supplied
with it.
Surface film buildup
Look for any accumulation of surface bio-film. This occurs naturally
when light organic compounds, such as fatty acids and insoluble
proteins, concentrate on the surface. The Red Sea MAX filtration
system continues to work even if the water level drops 5cm/ 2".
To ensure proper surface skimming, adjust the level of the over-
flow box attached to the filter comb:
1. Lift the hood and secure the supports.
2. Adjust the position of the over-flow box so that the top surface
of the teeth is at the water surface.
3. Pay attention to the water level in the filtration chamber and
adjust the over-flow box as necessary.

Algae blooms
Look for any signs of algae blooms green filamentous,
cyanobacteria or diatoms. Both desirable and undesirable algae
will thrive in your tank which provides the perfect conditions for
growth: water, light, nitrogen and phosphates. Algae control
techniques range from preventive to biological, mechanical,
physical and chemical.
Different algae serve different functions. At the basic level, they
serve as biological indicators, giving you signs of overall system
health. The algae in the system generally include the following
types:
Diatoms
These ubiquitous, single-celled algae prove mostly beneficial in
nutrient cycling, out-competing undesirable organisms. They
appear at the first stages of the cycle period, as described in the
previous chapter. Though they may appear as a brownish film
on tank walls, live rocks and gravel, diatoms rarely cause problems
in marine aquaria. They proliferate under high silicate conditions;
they consume the silicate and reduce its level.
Blue-green, cyanobacteria
These organisms actually appear dark red to the naked eye.
Closely related to bacteria, these algae often constitute the scum
on polluted, poorly aerated or circulated, over-fertilized waters.
