I have multiple feed schedules where I may I need to keep my skimmer off for longer period of time.
15 minutes is my main one and this is when I fewd the fish
45 minutes when I am broadcast feeding coral.
I have three maintenance plans
1- 2 hours shut us off the skimmer turns on the sump light under the cabinet. Used to clean out the skimmer cup.
2- sump light on, return pump off, UV and chiller off. This is when I am doing maintenance in the sump. (2 hours).
3- poweecut - reduce all pumps by 50 percent, lighting by 50%, and turn off all non essential devices until power is returned.
