Currently have a ozotech poseidon 220 running on my 500 gallon tank. It's basically running 24/7 as my ORP never reaches the shutoff point.

Any suggestions on generators for larger tanks?

I have the 220 on my 600 system.It runs 24/7 and reaches my cutoff of 440 once or twice a day.
-What is your cut off?
-Are you running dryer media? (I am)
-are you pushing air through it with a small air pump? (I am)
-is it plumbed into your skimmer?

Ricardo is pretty spot on with the questions. The last time that I used Poseidon 220 was on a 300 gallon aquarium with another 50 or so gallons of water and it performed quite well. I was pushing air through it into an ozone reactor. Of course there are other ozonizers out there, but I am curious to your answers concerning Ricardo's questions, before saying anything else.

i have a 25mg attached to my skimmer on a 1400g system seems to be enough. to achieve my desired rx of about 300 it takes around a week after a water change. to deal with issues i have a powerful 120w uvc as a backup plan.

cut off is 450
yes, running an air dryer
pushing with a small air pump
it's pushing through a Geo OZ818 ozone reactor

my ORP typically maxes out around 380 overnight and then drops from there

That is not a poor number.
I have my Generator output at aprox 60%
