LGMAquari 's equipment is a synonymous of quality, reliability and ease of use.
BRead these simple instructions to appreciate LGMAquari experience and use your new skimmer to
the best.
Geppy Apuleo - LGMAquari Product Manager
Do not power the pump if dry. You may damage it.

To lower any noise from the clean water outlet , it’s better to
use a pipe with a diameter the same as the drain hole’s and long
enough to take the drain outlet to the most appropriate place.
Plug a“T”joint with one hole upward-facing; another vertical pipe
can be plugged into the“T” joint and immersed into 2cm (< 1”)
water so that the drain outlet will become totally noiseless. If you
use a 90° joint instead of a“T”, to maintain proper stability of use,
it will not be possible to immerse the vertical pipe in any case.
LGMAquari 's skimmers are equipped with an exhaust system which is adjustable in height .
This type of exhaust allows to customize the skimming, changing the amount of treated water without
changing the water level inside the contact column . This will avoid any wrong bottleneck.
Always keeping the water level in the contact column A at the right level and the drain outlet 5 free
from any obstruction are the essential requirements to keep the skimmer properly working.

All LGMAquari 's skimmers have been designed to be placed inside or outside a sump tank.

2. Positioning & Installation
Turn on the water intake pump connected to 2 and wait until water begins to overow from the drain
outlet 5 . The drain outlet may be extended depending on your needs and/or deected with specic
ttings. The drain outlet can be extended horizontally and/or vertically, but never upwards. The end of
the drain outlet must always be at least partially out of the water in case of use of an 90° joint while
may be partially immersed (up to 2cm- 1") in case of use of a “T" joint. The adjustment of the amount
of water treated and the levels must be done with all ttings mounted.

Never install a system to pump water from the aquarium, through
the skimmer and back to a lower-levelled Sump.
If the return pump from Sump to the Aquarium get stuck, the Sump
tank will overow and the Aquarium tank will be emptied.

Adjust the amount of water ow, using a valve or the ow regulator of the water intake pump
connected to . The ow must be adjusted according to the here below table and your skimmer
model.
LGMAquari 's skimmers can achieve dierent performances, by working on several ne calibrations.
You can obtain very dierent results by acting on the adjustments of the air, amount of water treated
and the level in the contact column.
Correct air ow Wrong air ow or level in A too high
For ne adjust, use a graduated bowl to measure the amount of water owing from the outlet pipe H .
Manufacturers always report a ow value for their
intake pumps. This is not a valid reference to setup
the skimmer. Once the water ow rate is properly
adjusted, rise or lower the height level of H to
bring the water level inside the column D close to
the base of the Contact Column neck. The water
should not ll the neck (water must ll the conical
part of the Contact Column , without entering the Collector Cup neck B ).
Turn on the pump and adjust the air ow through G in order to obtain a foam, not too dry but very
dense and dark. The air adjustment is empirical, according to the organic load of the tank, the skimmer
model and some other minor factors.
Correct water level

you completely removed any trace of cleaning chemical agents.

• Keep the drain outlet free from any obstruction
• The best skimmer performances are obtained if the water intake pump is placed in a compartment
with water at a constant height, or by using a high prevalence pump
• The skimmer needs at least from 3 to 7 days of startup to work properly, effectively and steadily
• A too much quick Collect Cup B ll-up means a wrong skimmer adjustment. The reasons for this may
be one or more of the following typical installation mistakes:
• Too high water level in Contact Column A (see chapter 5)
• Too high air ow from G (the foam will be too wet - see chapter 5)
• A too big and sudden organic load for the current calibration
• Some rubber tubes, even if not connected to the skimmer, may release substances that may inhibit
the skimming process. It is strongly recommended that only tubes specically designed for aquariums
and for food should be used.

7. Maintenance
www.lgmaquari.it | [e-mail]
!
Before lifting the skimmer, if lled with water, empty the skimmer before lifting it by
by unscrewing the tting and put aside to help water pour out. In case of lifting
with water inside, place one hand below the bottom base of the skimmer and the
other along the Contact Column . Never lift up the skimmer from any upper edge.
To ensure your skimmer is working properly, it is essential to perform some simple periodic mainte-
nances. This is essential to maintain the aquarium healthy.
• 7.1 Contact Column cleaning
Periodically wash the inside of A with bleach (chlorine-based products) to remove any traces of algae
which inhibit the skimming. Also residues of calcium deposited on the inside will inhibit skimming. To
remove them, perform a ush with diluted hydrochloric acid or vinegar.
• 7.2 Air suction block cleaning
Periodically or in case of very low air ow, clean G and the connection rubber tube to F .
Calcium and/or salt deposits may progressively block up these parts.

Before reinstalling and restarting the skimmer, rinse well all the parts and make sure
you completely removed any trace of cleaning chemical agents.

• 7.3 Skimming pump cleaning
Important attention should be given to the pump E . Between the ceramic shaft and bushings you
will have calcication deposits, as well as in the compartment of the pump impeller. These deposits
will cause frictions, noises, overheating, a premature consumption and quick decrease of the skimmer
performances. Periodically, and in the case of precipitation of calcium (kalkwasser, etc.), you must
perform a strong washing of all internal components with dilute hydrochloric acid or vinegar.

• 8.1- Turn off and disconnect all electrical equipment in the Acquarium and/or Sump before carryng
out any maintenance tasks.
• 8.2 - The power cord must not be repaired or replaced. if it is damaged, replace the entrie pump.
• 8.3 - Always check the voltage on the pump label to make sure it corresponds to your local main
power supply.
• 8.4 - The pump can not be left to run dry.
• 8.5 - When the pump is plugged into the mains, make sure the lowest part of the lead is lower than
the socket. This is to prevent accidental spillage of water running along the lead and reaching the
socket.
• 8.6 - We recommend that the pump and all…should be connected to a grounded circuit breaker with
a 30mA fuse.
• 8.7 - The skimmer must not be used or disassembeld without the supervision of an adult. it’s not a
toy.
