We have taken a few power hits during the latest storm and I am afriad it
will blow my
lights... does anyone use and UPS on their tank ?

Yes I have a back-up power supply for the main pump. It works for
about 15 mins before it is exhausted.

15 minutes? I would say your UPS is not needed at all.
You could leave it not working for 15 minutes and it would not harm the tank...


The reason that it is useful is that when the power goes off, the sump
fills with water. When the power returns, the in-sump protein skimmer
will overflow onto the cabinet floor a significant amount of water.
