Aqua Ultraviolet UV Sterilzer with Wiper -- Anyone own one?

[mordred]

I am thinking of buying the 25 watt model for my 140 gallon freshwater tank that's running at 700g/hr. So far it looks like high initial cost, but lower cost on replacement bulbs.

One of the hangups is the option for the inlet/outlet size. I would assume that I get the 3/4 inlet/outlet since that is what my return water vinyl tubing is.

Also, what was the best way for mounting these bad boys for maintenance, etc.?

Thanks!
