Are UV sterilizers good for saltwater aquariums?

How long should I run my UV sterilizer?

How do I choose a UV sterilizer?

The greater the UV power per unit of water, the better the sterilization effect; the greater the flow rate of the water through the UV lamp sterilizer, the greater the total sterilization effect; the greater the UV254 transmittance, the better the sterilization effect.

What size UV sterilizer do I need?

The maximum flow rate should be greater than the number of gallons in the system (tank & sump). For example, if you have a 100 gallon tank and want to control parasites, you would need a minimum 18 W UV with a maximum flow rate of 100 gph. A 25 W UV at a flow rate of 150 gph would be preferable.
