36-40 watt U.V. Sterilizer

[Old Man Of The Sea]

Here we have the next topic for the rebuilding of my 240 gal reef tank, something that came up when i ask my aquarium man on what other equipment should I be looking for, and the equipment part he mention is a U.V. Sterilizer. Now the tank is 240 gals and the sump will be a 125 gals, im thinking I want to be looking for is a 36-40 watt U.V. Sterilizer, is my assumption correct? And which is the best to have?

I taking notice of one thing different with the models here, some are with wiper and without it. What is the difference between the two?

Who can even suggest other U.V. Sterilizers, your suggestion be most welcome.

This part is nothing to do with this topic, its about the overflow and bulkhead that if it should be impossible to be made larger, then I would need to look into another return pump, or two return pumps as James was first suggesting about, only I not want the quiet one or the eheim pumps.

I don't use UV anymore, but I can help with some of your questions.

The wiper is what it sounds like .... it's a feature that allows you to "squeegee" the quartz sleeve so it's clean. This is a nice, useful feature I'd get to optimize your UV performance and minimize maintenance hassles.

I've heard various unit endorsements from different people, but there's no empirical data on performance differences. I really wouldn't know which one performs better. UV sterilizers are pretty simple devices, so I would expect with the same pass-through rate, one unit is not going to perform very differently from another.
