Q. My set up is not new and skimmer isn't producing foam or it is too
dry and builds on the neck.
A. During a new set-up the bio-load is low and the amount of organics
®
is negligible. If your MAX is fully stocked, increase the height of the
skimmer shutter as necessary and open the air valve. Check the water
level in the rear filtration chamber and raise it to the optimal line. If
you still get light foam production inspect for blockage in the airline or
skimmer inlet.
Q. My skimmer is not new and is over-skimming after feeding and/or
supplementing.
A. See Feeding and Supplementing in chapter 11 (page19).
Q. The water level in the aquarium is too high.
A. Check the surface skimmer comb for restrictions such as algae or snails
and clean the comb as instructed above.
Q. A pumps has stopped working or is making mechanical noise.
A. Disassemble and clean the pump as instructed above.
Q. The circulation pumps are injecting micro-bubbles into the
aquarium.
A. Make sure that you have added freshwater to compensate for
evaporation and that the water level in all compartments of the
rear sump is correct and that there are no blockages in the surface
skimmer or in filter media preventing the pumps from being fully
submerged. A low level of micro-bubbles in marine aquariums is
normal and should be expected. Intense skimming is the secret of
great water quality, as it both removes organic waste before it can
break down AND maintains a high redox level. This is achieved by
super-saturating the water with air, i.e. dissolving more gas into
the water than is normal for the given temperature and pressure.
Once the super-saturated water leaves the skimmer, it "relaxes"
and releases the extra gas in the form of micro-bubbles. In the
®
MAX C-Series the pumps are located near the bottom of the
sump and are pre-filtered by a sponge that should prevent any
air bubbles from reaching the pump inlet. There may be a buildup
of air trapped inside the sponge. Remove the sponge, rinse and
return it to the sump. You might be getting micro-bubbles if you
are using tap water with water conditioners or natural seawater.
Many conditioners, some synthetic salt formulae and impurities
found in natural seawater increase the surface tension of the water
and cause a small proportion of the bubbles to escape out of the
skimmer chamber and flow out through the pumps. We strongly
recommend NOT using tap water. If you are using tap water DO NOT
add conditioners or de-chlorinators.
Allow the water to settle for 24 hours to let the chlorine evaporate
naturally before introducing to the aquarium.
