When I used this skimmer on my bc32, I started with the skimmer higher than needed for a about a week, so the skimmer could break in.
See below for a rough place to start with where the skimmer needs to sit.
Blue line is the water level
Red is to point out the hanger and that it needs to move down to “raise” the skimmer up.
Set the skimmer so that when it is running, the water/bubble mix inside is about an inch from where the collection cup meets the skimmer body.
After a few days, you may be able to “lower” the skimmer some. Or you may not need to. What you want to look for is where the bubbles pop and where the “nasty foam” (it will have a brown tint to it) forms. By moving where this foam forms up or down on the inside of the skimmer determines a wet or dry skim. Higher up in the body is more “wet” and lower down is more “dry”.
for now, with the skimmer being new, it will go nuts for a bit. This is why I suggest raising it up for the time being.
