Ozone is an extremely aggressive gas which - if not used properly - can damage one's
health. For this reason, ozone should never be breathed in directly.
In addition, at high doses ozone can damage the skimmer.
The dosing of ozone must be set so that no free ozone can be discerned on the skimmer lid.
Deltec skimmers can be operated with 50 mg/h of ozone per pump. An ozone-resistant T-
piece (Glass) should be fitted in the air hose above the skimmer pump. The free end of the
T-piece is connected to the ozonizer by means of an ozone-resistant hose.
In addition, if necessary (depending on the skimmer) an air valve must be installed.
It must be throttled until air is independently sucked through the ozonizer. The Skimmer
can be operated with ozone up to max. 50 mg/h per pump. The air connection of the
ozoniser should be connected via a suitable silicon hose to the protein skimmer pump. The
air is automatically sucked in the ozoniser by the skimmer pump. Should the skimmer
performance deteriorate please check the ozoniser for blockage.
Safety information:
The maximum ozone quantity of 50mg/hour per pump must not be exceeded.
-
The air passage can be reduced as a result of dust deposits in the ozonizer. This can
-
result in an increase in the water level in the skimmer, which - in extreme cases - can
overflow. To avoid this, check the ozonizer regularly to make sure that there are no
deposits of dust. If necessary, clean it.
Never breathe in free ozone.
-
The ozonizer may not be directly connected to the air valve.
-
In order to avoid water damage, the ozonizer must be placed high enough to ensure
-
that no water can penetrate it when the skimmer pump is switched off.
If the skimmer is used with new water on an aquarium it is common for find an excessive
quantity of small bubbles and often the skimmer cup fills with a clear liquid. This is due to
the high surface tension of the new water which prevents the bubbles from bursting. Once
the water matures this effect will go away but can take up to 2-3 weeks. The effect is
different on different salt brands and is often dependant on levels of conditioning agents
added to the salt. Once these are skimmed out then the skimmer will act normally.
Heavier feeding in the initial stages will give the chemically pure water something to react
with and allow it to mature into proper aquarium salt water rather than the initial chemical
soup which is new salt water.
