How do u put it on low setting?

Just turn down the air flow. Usually a little hose with a valve of some kind coming off the air pump. With HOB skimmers anyways.

Yeah theres no valve lol theres the hose that comes off the pumps intake, that has a black silencer on the end of it

Got my little 15 gal premix setup, with a maxijet 400 to mix and then when the time comes i bought some hose to attach to it to pump it into my tank

Nice and cheap mixing container
Looks good

I may have missed it ... what skimmer are you using ?

OH, nm, I see it
RO 100

Kinda hard to see them, but will microbubbles go away after break in? One of the reasons i bought this skimmer was because all the videos and reveiws i seen ppl said they didnt get any microbubbles

Some quick reading on the web shows me that you may want to add an air valve to the air intake so you can fine tune it
Some suggest nearly closing the air intake altogether to get great skimmate

You can use something like this if it's standard airline tubing sized

They usually diminish in a week or two. HOB skimmers are pretty prone to having some micro bubbles but after the break in period it's not usually a problem on the better models. I went with the Aquamaxx over the Reef Octopus model for a HOB skimmer mostly because I liked that I could point the discharge pipe against the back aquarium wall so any micro bubbles that were present didn't get pushed out into the tank.

Im hopeong that as i raise my water level the bubble trap will work better, its just one of the 3 sponges that are actually in the water right now, been waiting to add water to see my salinity was at cuz i just got my refractometer today. Set up my pre mix tank and mixed to 1.025, gunna let it sit amd stir over night and add water tommorrow afternoon amd then try amd fine tune the skimmer. My intake tube is currently bent almost horizontal because my water level isnt high enough for it to be on the proper vertical possition

You got nothing to worry about. Like everything in this hobby it just takes time. You got a great hob skimmer and after it's been running for awhile and you have everything set up correctly you will see some nasty gunk being pulled out of the tank.
