Is there such thing as too much UV sterilization? Like say 25- 50 watts on a 120 gal w/refugium. Maybe put it on a timer?

Probably at some point, but it’s nowhere near there. I wouldn’t worryIs there such thing as too much UV sterilization? Like say 25- 50 watts on a 120 gal w/refugium. Maybe put it on a timer?

See this thread from around post #28.

Just wondering, why would it be bad to put even less gph through the UV Sterilizer than suggested by the manufacturer? Is there a negative to UV sterilizer's working too well? I know the debate out there seems to be that they are un-necessary because they usually don't give a long enough...www.bareefers.org
That is definitely not too much for your system from the standpoint of too much UV treatment. You can get into problems with heating when you oversize, since UV sterilizers put in about as much heat as a heater of the same wattage. Generally recommended to run continuously. Something in that range would be most people’s target, and the lower end of your range is less than many people would suggest.Is there such thing as too much UV sterilization?

Less heat?It is often better to only run part of your returns through the UV.
Let say you do half.
That means the probability of a bad microbe being killed each time is 50% of what it was.
Because it may go the other way.
But it is repeated over and over. The odds of that coin flip being all heads for 100 times gets low.
On the other hand, you double your dwell time.
That can take you from being ineffective (0%) to effective (100%) if you hit the kill threshold.
And it saves money, less heat, and no issues with return flow.
Because you can go with a smaller UV.Less heat?
I don't see the logic as to why half is betterIt is often better to only run part of your returns through the UV.

Not sure this logic is correct. I thought The flow rate dictate the exposure time. Each organism will have a certain exposure time to die from the UV power otherwise it will pass...It is often better to only run part of your returns through the UV.
