How do I set a Cpr Aeroforce skimmer?

[sumpfinfishe]

Yes the height of the cup will also determine what is being collected, if the cup
is too low the skimmer will produce too wet of foam(clear liquid) as if too high it may not produce
enough liquid so adjust a little at a time to find the happy medium. As for making it quieter, im sure if you google the skimmer with mod at the end you may find some trick to slience it a little, however all skimmers will make some noise due to mixing of air an water at high
rates.
