gradually as shown in gure 23c.
Attention: It is advisable to adjust the collection cup by small movements, one at a time (2/4mm – 1/8/1/4 in).
For every adjustment you need a few hours before verifying if the foam suits the needs. Repeat this operation
until you reach the correct setting without going beyond the min and max level shown in g. 23b and g.23c
AIR REGULATION:
Air can be regulated by adjusting the control (T).
Air regulation is very empirical and depends on the aquarium stocking, the type of foaming desired, etc.
Slimskim was designed to operate with the air ow control completely open to optimize ratio between air
volume, foaming chamber size and quantity of water skimmed.
Warnings
Before removing the skimmer, empty the collection cup to prevent the waist from accidentally falling in the
aquarium. Always operate "Slimskim" with the lid and the air intake tube correctly positioned.
Attention!
Maintenance
ATTENTION: Before placing hands in the aquarium, always disconnect from mains all electrical
devices immersed in water.
Regular cleaning and maintenance of the skimmer and the foaming pump will guarantee better performance
and durability.
Please follow this list of activities:
Check the collection cup and clean it on a regular basis;
Periodically clean the column with water to remove any trace of algae. Only if necessary, use bleach, diluted
hydrochloric acid or vinegar to remove algae or calcium residue (which could inhibit foaming). Remember to
rinse thoroughly to avoid any detergent residue. Attention! This operation (cleaning with detergents) takes the
skimmer back to the initial conditions: it will take a few days for it to return to desired settings and e ciency.
Regularly, or when the air ow diminishes, clean the air intake tube and the control (they could become blocked
with calcium, salt or dust residue).
Special care should be taken of the foaming/supply pump. Correct maintenance will guarantee durability of
the impeller and less noise. Calcium residue could form between the shaft and the impeller, as in the impeller
chamber. These residues can cause friction, over-heating and premature ware and tear compromising the
components and correct functioning. For this reason and in case of calcium precipitation, use of Kalkwasser, etc
the pump and the impeller should be washed in an acid solution such as Hydor MagiKlean.
Following these procedures will help maintain Slimskim e cient.
Quick trouble shooting ...
Excess foam production: adjust by lifting the collection cup and lowering the o-ring gradually as shown in
g.23b. Check air ow and if necessary, reduce.
No Foaming: adjust by lowering the collection cup and lifting the o-ring as shown in g.23c. Check air ow and if
The air tube should always be positioned correctly on the collection cup
lid and should never hang over the side of the aquarium to prevent the
drainage of the aquarium itself (communicating vessels e ect).
