Kinda know how they work but have never seen one in operation. I purchased a SCA 301 from SC Aquarium. Realize there is a break in period and may have to lower/raise skimmers water level to achieve best results. Since never seeing one work.... Where are the micro bubbles supposed to pop, just before the lip or a measurement down from the lip. Is that how to fine tune skimmer to do a wet or dryer skim...not sure, but makes sense. See I need to lower mine to raise water level (at 6 in now) bubbles are not traveling up to the collection cup with this current egg crate stand. Going to youtube it but wanted to ask here also....Thx
