I am using the second hose came with the skimmer which normally should be used from  silencer to the pump so i can get closer to the rear of the cabinet and getting more fresh air plus the noise on the silencer is more less.
The strange thing is that i get nothing on the collection cup on this level and i am thinking that the skimmer is to big for my setup or i don't have so much dirty in the water due bioload is not that big.( 12 fish some snails and 20 corals most of then frags).
Thinking on turning the skimmer of for 12 hours and then to see what i get.....

Yeah I know the hose , you could probably rule that out for affecting bubbles . Personally I'd leave it , it won't produce anything if you turn it off , but as you say it also won't skim what isn't there . The load on a skimmer is not a constant thing , once proteins are skimmed off the bubbles drop back until more are present . As long as your test results are in line with what your after I wouldn't worry too much about it . You shouldn't be looking for it to be bubbling over constantly . Leave it to run and be patient .

Here's another pic of mine , as you can see at the moment there isn't anything needing skimmed off and the bubble height is a little low

I will levae it like that for now and see how is going. My readings are all ok( actually no i am doing them) except a higher Mg which i am fighting with since i start the tank , it's between 1560 and 1600 bit thats a different story. Can i please ask you to upload ( when you have time) pictures with the water level on the skimmer chamber and how high it is( i know is is the 5 but at least i can make an idea) also a video on how fast the bubbles are coming up in the neck( i have the filling mine are coming to fast and i need to adjust the height of the skimmer)?

Here's a couple more pics , I've pulled the top off and gave the inside of the neck a quick clean so it's more obvious , hence it's lost the bubbles on top , I'll post a short video later as my internet upload speed isn't great .
Another thing to check would be the position of the clear circular plate above the pump outlet , it should be firing against the bit with no holes .

Thanks:

From what i can see on the 1st picture you don't get any bubbles under the perforated plate , all bubbles going straight up. On mine a lot of bubbles are coming all the way down and going out trough the bottom of the air intake dial.
I think due this issue i have all the problems with the water level/speed/size/overflows.
Do you remeber if you had this problem on the first weeks after install?

Yes mine was similar until it settled in , I was also adjusting it up and down trying to set it in the beginning , it's just because it's new , once it gets a bit of a film up the inside of the neck it settles down , I think from memory it was around 4 to 6 weeks . I still find that mine occasionally produces all the micro bubbles out the outlet but only with certain foods , think it's to do with the oils off the foods . It will also do the same if your hands are in the tank / water a lot as well as kill the bubbly head .

The other strange thing is that  i can't keep it in 26cm deep water. If i keep it on 26cm it will overflow continuous after 5-15 min even if the dial is on max and the only way to stop this is by raising up to 20cm deep water and then i can adjust the dial to 2 or even 1. It's all ready up and running for more then 5 weeks and still not settled. I will leave it for 1 more week but to be honest i start to look for an alternative.
 One more thing , now i am running  filter socks , do you think will be better to remove them and leave all the detritus to be removed by skimmer?  I have same filters between skimmer and refugium so not to worry about detritus passing on the refugium.

I started off with filter socks , but don't bother any more , I find my skimate is substantially darker due to this and IMO feel it's better to remove the dirt with the skimmer as opposed to having it sit in the filter sock for a few days .
I've never had any bother with the depth and hadn't even considered adjusting it to see if I could get a better skim . I think as an average for most skimmers 20cm / 8" is about the average depth for most skimmers .
I'm not sure with your skimmer being a little bigger than system volume if it would maybe take longer to bed in . I have read of a couple accounts on here of skimmers never producing anything possibly as the rest of their system is coping without it .

Today the seller told me to put the skimmer in 10" of water and just leave it to overflow and it will settle in couple days........that's last attempt....then switching to other model
