Glad to see this thread because after installing my new skimmer (ER-135)last week, I have YET to find a consistent level of foam. Either too low or too high. Driving me crazy!!!!!!!
Out of curiosity, do you have your sump set up so that the water level NEVER changes in the skimmer section?? If not, it is important to do so with any in sump skimmer to truly have it perform consistent to your desired wetness/dryness of skimmate. An ATO set up can helpw ith this, but the best way with zero play is to set up the first "over" baffle next to your skimmer chamber higher than the rest so regardless of anything, the water level cannot fluctuate where the skimmer sits.
