just received my 9410 skimmer and i am reading about some booster ring to fine tune the skimmer. Where is this booster ring i keep reading about?

It is inside the filter bag holder and allows you to set the height, especially when new you will want this to be flush or below the top of the pipe, raising it raises the internal water level of the skimmer and a new skimmer you will likely just bog down the anti overfoaming system as the intermediate chamber will fill with water, on a 9410 this adjustment is very rarely used unless it is older and worn and not at peak performance.

thats what i was thinking it was but was not 100% sure.

do i have to run this with the post filter attached? It is kind of in the way of where my drains run into the filter sock

What is the optimal water depth for this skimmer? I have been reading Ali about how sensitive this skimmer is to the water level.

any ideas? Looks like my sump skimmer compartment will run between 8-9 inches

I plan to run it through a vinegar solution to help remove any manufacturing oils unless you dont recommend this. If not i will run it in a rubbermaid tub of old water change water for a while to speed it up
That would help, especially if the water was on the warmer side. But when new everything is optimal and it is not just the hydrophobic properties of the new plastic that are an issue, the pump is at full power, the airflow is ideal, by this alone it tends to foam a bit excessively when submerged deeper, after a couple months when the impeller is dirty and the air line has fouled a bit is when the water level can be higher. You can try it, but my experience is the skimmer is easiest to tune in roughly 7" of water.

can the foam not be controlled by the adjustment screw on the airline? or will it still produce a lot of foam even mostly closed?
The valve only adjusts the ratio of air to water and the issue is that by closing the air you increase the water flow and the submersion depth will reduce this because then the pump has to fight the column of water in the body, if the body is submerged more, their is less "head pressure" against the pump.

just turned on the skimmer. i set it into 7 inches of water that i pulled out of my 75 gallon while doing a water change. how long does it take for the bubbles to actually get into the cup. From what i was reading online i figured it would have foamed over in a matter of moments.

how do i get this tuned in properly? went from not foaming high enough to foam like crazy back to not high enough in a matter of a few moments.
I wouldn't expect much result as the organics in the water will decompose leaving little to skim. I would consider this just seasoning the plastic. When you actually install it, 7" water level, air adjustment closed about halfway and the filter bag attachment level with the top of the pipe. Keep an eye on the water level in the intermediate chamber, in an over foam, this rises and shuts off the airflow, this is normal but will be the cause of foam over/ no foam cycles during break in or when certain additives have been used. It will take some hours to form and collect any real skimmable foam.

so i set this up on my 75 until i get the 220 setup and i just dont get how one minute the foam is going everywhere and then the next time i look its not producing foam at all. Just very frustrated with this thing. I have never owned a skimmer this hard to dial in during my 15 years reefing
The air hose is connected to an intermediate chamber, this chamber will shut off air flow during a foam over, I suspect that is what is happening. Pics of the skimmer installed will help a great deal but most likely the issue is simply that some surfactant is present, an overfoam occurs and then the auto shut down where water blocks any further air flow. You can bypass this if you wish for break in by just disconnecting the airline from the port on the side of the skimmer.

my sump on my 75 is a blue rubbermaid i can't get pics from the side only the top of the cup. What you described is what is happening. it overfoams then stops for a few seconds then overfoams again. I tried closing the valve on the airline but that made the skimmer produce even more foam than when opened all the way
Is it level? Usually with those rubbermaids they are molded and bowed in the middle and have support ridges around the edge, if it is not level it will border on impossible to tune. When you close the air, you do increase the water so it is a balancing act, I think the main issue is that it is likely not sitting flat.

i will check that later. if it is level what could it be? just time to break in properly?
