With new skimmer they take a couple weeks to break in.
Break-In Period
Now that the skimmer is properly installed and running, You should allow the skimmer to break in for a minimum of 2 weeks. During this initial break-in period, water will slowly wash off all inert oils that come directly from factory handling as well as coat the inner walls of the skimmer with live bacteria. Be sure to leave the skimmer valve mostly open during this period and do not attempt to tune the skimmer, doing so too early may result in inconsistent performance and possible overflow.
Once the break-in period has passed, you can tune the skimmer to your aquarium by simply turning the output valve clock-wise until you obtain pea size bubbles at the point where the collection cup meets the skimmer body. Allow the skimmer to acclimate to the new setting for 24 hours before making further adjustments. The more you close the output valve, the more wet the collection will become.
My protein skimmer is overflowing. Why is this happening?
The most common reason for skimmer overflows is caused by a Chemical Reaction. Some chemicals react with the air that the skimmer produces and causes the skimmer to over produce foamate. Chemicals known to cause skimmers to overflow are, red slime remover, medications, frag putties and coral glues, water conditioners, dechlorinators, stress coat, NEW filter socks, newly mixed salt, bacteria additives as well as other dosing medias.
In order to remove these chemicals from the water column we suggest that you do several 20% water changes over the period of a month and add a good amount of fresh activated carbon to the system and change out every week till the skimmer has returned to normal operation.
