I have been looking at raising my nutrient levels without dosing and one of the options I am looking at is running the skimmer on a schedule. Doing some searching I see lots of positive results in SPS and LPS when the skimmer is turned off. Common sense tells me that skimmer should go off at night when coral polyps are open the most but what about the PH swing at night? Also for those that do turn it off what about the evaporation and return chamber water level changing? I would love to hear some long term results from those running on a skimmer schedule.
