Affordable UV Sterilizer

  • We are currently upgrading MFK. thanks! -neo
The effectivness of a UV sterilizer is dependant on the power (wattage) of the UV bulb and the flow rate of the water going through the sterilizer. The higher the bulb wattage the faster the flow can be. With a low watage UV bulb you are going to have to have a very low flow.

I chose to go with a DE filter (in my sig) instead of a UV sterilizer. After many many years I have never had a diseased fish.
 
How big is the tank? Aqua UV is a decent brand and 15W is probably enough for 75 gal.

Too low of a flow rate will be ineffective. Studies show faster is better. You can't compensate for low watts with low flow rates in recirculating systems. That should be fairly intuitive.
