I picked up a ASM G2 skimmer for use on my 40 breeder with 20L sump... and I am stuck. lol 1. its and extrememly tight fit and creates so much bubbles I have them goin in to my main tank so I think I may have to redesign my sump to accommodate it and its bubble making power.. 2. Its leaking around 2 seams making it not fill up so much in the chamber. Does anyone have this skimmer they are using and could give me pointers on how to get the ball rolling good?

The one I had never really "sealed" up around the connections. It was an "in sump" skimmer if ever there was one. Could always do the gate valve mod on it, might help with bubble control.

I dont think there would be anything wrong with using aquarium silicon to seal those joints.
as far as the bubbles go.... you may try a sponge in front of your return pump if space is limited.
ALSO, my euroreef always made more bubbles if the gate was opened less (LESS water in the chamber). YOu may try opening your gate some.

The whole point of the "seals" is the whole thing can be taken apart for cleaning. Silicone might work...once, lol.

Oh i misunderstood. good point though haha
I purchased a ASM G1. Same skimmer just a little smaller than yours. I posted a very similar post in reference to the operation of the skimmer due to the fact that it came with no directions. The responses I received were very similar to the ones you’re getting. Just as I was about to chunk this thing and purchase something else, I contacted the store that suggested it and installed my tank. They gave me some very good pointers.
The skimmer is very sensitive to sump water levels and contrary to prior belief the height of the internal water level has very little to do with the pump connections. In reference to your question about the water height in the main tube. The first thing you should do is take a look at the exterior tube (kinda looks like a waterfall) that has the long circular sponge attached to it. This tube is 100% adjustable and can be removed . The higher you pull the tube up the higher the water goes in the cup portion of the skimmer and vice versa. I suggest using a clean rag or paper towel in order to assist you with your grip. To the best of my knowledge, this thing flows wide open all of the time so there‘s no real way to control the froth of the bubbles.
I adjust the external water tube daily in an effort to assure that it is still working properly.
As for the bubbles being returned to the display, I purchased a large sponge and cut it to fit under the waterfall portion of the skimmer and in front of the tube leading to my return pump. This eliminated the vast majority of the bubbles for me.
Let me know how this works.

I thought this skimmer worked just fine. It doesn't need directions, it's a pretty basic skimmer, pump water and air in, let water out, adjust exit tube to height desired for wet or dry skimming.
I would argue that this is how 99% of skimmers run, pumps wide open pulling and chopping as much air as possible. Most skimmers of this design (read: not external) are sensitive to water levels because it affects the back pressure on the water inside the body tube. A properly set up sump will have a skimmer chamber where the water will remain a given height (usually between 8" and 10"), so you can adjust the skimmer once, and then not worry about it.
You can add a "gate valve mod" to the exit, which allows more precise control of the water height inside the chamber.
Skimmers make bubbles, it's what they do. The best bet to eliminate them is to have the output tube as far away from the bubble trap as possible, and again, having a properly set up sump and bubble trap helps to this effect.
it came with a gate valve mod as well as the piece with the foam thingy. also, i do believe i made the skimmer section 8.5" or 9" high... its been a while since i even looked at it. so that water in the skimmer area is pretty much set it stone.
I'm probably gonna have to redo my sump anyway since it was thrown together in a few hours when i first did it. bad part is.. the only way to get the sump out is through the back and that isn't happening. I would cut it to slide it out but i wouldn't know where to start.

One thing you can do to to limit the footprint of any of the skimmer that use uniseals (ASM, Euroreef, etc.) is ditch the elbow and mount the pump directly to the side of the skimmer. Just insert the output of the pump into the uniseal. It's makes it a little more difficult when it comes to maintenance but it will save a few inches in the sump!
