Recommendations
While we take great care to keep any contaminants away from our products during assembly, please take a
moment to clean before attaching them to your tank. Please clean with warm water ONLY. Never clean Acrylic
with alcohol-based products. Use caution when handling acrylic scratches easily.
It may require 2 – 4 weeks for the skimmer to reach optimal performance due to tiny amounts of oil or
remnants left from manufacturing. Skimmer performance may be erratic during this time; be sure to allow
ample time for the skimmer to break-in before making adjustments.
Regular maintenance of the pump will ensure a long life and maximum performance: recommended every 3
months.
For best performance, clean the collection cup frequently with a sponge and warm water.
Loosen the screw to
pick up the sponge of
water outlet, make sure
to keep it clean.
The air hose needs to be clear all the time, check the connected part
with the silencer often, once it’s clogged, you can clean it right away.
Sometimes the silencer got clogged by limescale or unpredictable
foreign matters, clean it regularly or anytime it needs. You can pick up
the silencer by loosening the screws marked on the image.
Clean the water intake
frequently to prevent it
from being clogged.
