Got all the parts of the tank. The return pump, skimmer and chiller have been installed.
Pump and Chiller are running fine, aquarium is general is not very noisy, the Chiller does make some noise but not too much.
As for the skimmer, at first it had a lot of foam and filled the cup in about 2 hours, just cloudy liquid. I switched off the skimmer and emptied the cup.
After starting the skimmer up again I can see that it is on and the skimmer pump is working and there is water coming out of the outlet pipe, however there is no foam in the cup at all. I tried adjusting the skim regulator and it did not appear to make a difference. This was late last night so maybe I was not giving it enough time. Also with being a brand new tank, no fish and no live rock maybe there is nothing to make the foam after the initial startup.
