Coralife super skimmers.....are a pain

[Manny]

mine works great. i have the 220 model and it is in a sump. the wter in the sump comes up to about an inch under the rim of the main rection chaimber. i cut the tube between the pump and the main chaimber about half its original length and i have the bubbles in the reaction chamber go just under the collection cup. i hope this helps.
