So I need to come up with a plan for a scheduled power outage at the school. The power will be down anywhere from 30 minutes to 8 hours. I am not sure what to do other than buy a generator or borrow one from facilities and hook up some flow pumps and air stones. My other fear is that I am not sure the sump will hold that much water. I did power test it prior to calling it good when I set up but I am still worried. Looking for thoughts and advice. The other problem is that I am supposed to be out of town that day.

Rent a generator for a day and run extension cords from it outside, to the tank?

Anything that can be done to mitigate back flow to the sump? If you could get generator from facilities, that seems like good option. But it would be nice to have eyes on things during the outage and also when power is restored to make sure everything comes back on line properly.

Sounds like they may just run it off of a massive natural gas generator. We’ll see!

My big worry is the sump not being big enough? You need to lower the water level in that bad boy... you don’t want to soak the floor in a summer hail storm...

For now the generator will do fine for flow and such, you may want to limit the lighting depending on how big the generator is. How many halides do you have on that?

I would personally limit the amount of electronics running on the generator. Only the essentials given that it’s a relatively short outage.

I’m sure the generator is big enough to run everything you run daily on the tank. However, my experience with generators is that they can put out “dirty” power. It depends on how well regulated the AC output is. (Is it a clean sinusoidal wave at 60hz at the appropriate voltage?) I lost multiple pieces of electronics overseas because we so frequently had to rely on emergency backup power. These were supposed to be quality industrial sized generators. Still trashed electronics I wasn’t running through a UPS that cleaned up and regulated the AC signal.

Again, my approach would be to limit the potential damage by only running essentials. Don’t risk blowing up your Apex or ballasts with surges or brown-outs.

Just my $0.02 :)
