Ozone Systems:

In the photograph you can see how the Ozone Generator is mounted in relationship to the Protein Skimmer.

Please note the higher level of the Generator to prevent water back syphonning in the event of a power failure.

You can clearly see the vent pipe which is fitted to the top of the Protein Skimmer .. it is very important the any system that you may
be considering installing is fitted with a vent such as this one ... the purpose of this vent is to transfer the expended Ozone gas into
the atmosphere..

The inlet for the water which is being pumped through the system can be taken from the last biological filter in your own system - as this water is probably the cleanest thus ensuring that your system will not be clogged up with particles of dirt etc... 

The supply of water being pumped through the actual Ozone Generator is not shown on this photograph and is 'T'd off the upright 1.5" pipe just off the photo... but you can see the primary venturi at the top of this pipework and this venturi is of course adjustable.
