I have a EuroReef ES5-2 skimmer and it has worked great for over a year now, but all of a sudden it is producing way too much foam . It fills the skimmer cup within a couple of hours. I have tried lowering the riser pipe to no avail. Even at it's lowest setting, it is still too much foam. Even removed the pipe with no effect on the foam . I lowered the water in my sump to get the water height down in the skimmer, but I should not have to go this as it has been working fine for over a year with the 20 gal.sump half full . Anyone else have this problem or have an idea as to the cause of this suddenly. Nothing has changed in my setup and nothing was added before this happened.I've also taken the skimmer out and made sure there were no restrictions in the riser pipe.
