Thanks for your replies everyone.....I moved my sea clown skimmer back to the top tank last night. This morning it had some foam and very little water in the collection cup. the water was very light colored with some peices of dark brown stuff in it....I will include some pics...The skimmer IMO is still not working as well as what should be...I ordered the octopus NW110. It should be here this week. Also What looked like micro-bubbles was not comming from my sump. with the sump out for repairs it still looks like micro bubbles going around the tank......there is defintaly something strange in my water. I hope the new skimmer clears it up....I am going to try to get the micron socks also.
