my coralife 125 skimmer isnt doing what i was expecting it to do. it does skim but doesnt overflow to the cup. it skims so much to the cone than it cant overflow to the cup. if i turn little more to wet side than cup gets overflow with nothing but plain green water. i got 3 fish so far, 2 wrasses and 1 purple firefish, not enough bio yet?:mad2:
