I am sorry but I can`t help more from here.
Many thanks fir you support - it's appreciated ..
I have learnt a great deal about the Profilux as a result of this problem !

I will contact Steve at Reefdreams to arrange for the repair..

I have also e-mailed my Tunze dealer to try to get the stream tested. In future I will only connect the streams to expansion cards as these are easier to have repaired / replaced.
