I discovered I am emotionaly attached to my skimmer and started it back up again
.
I did a water change the other night after changing the filters on my RO unit and immediately after the water change all the polyps on the corals withdrew, so in a panic I replaced the carbon and turned the skimmer back on. Everything is fine, it appears to be just a minor blip but I feel better leaving the skimmer where it is.
For the 2 weeks it was turned off I didn't notice any big changes
