I want to install a UV sterilizer in my pond, but would prefer to
construct it myself, partly because I'm a retreaded engineer, and partly
because I'm sure I can do it for considerably less than the cost of retail
units. Does anyone know of a web site or newsgroup that covers construction
details, experiences, war stories, etc. on the topic?


It shouldn't be to difficult I guess, the hardest would probably be to get
some UV transparent tube you could insert the UV light into, does anybody
know if clear PVC or clear Acrylic are 'clear' regarding UV, I think clear
Acrylic are but don't know with PVC.

You could make a system using a 1.5" inner clear tube and a 3" outer non UV
transparent outer tube, ie. black tube and some 3" to 1.5" slip fit reducers
and some 1" hose fittings clued into a couple of hoes in the outer type at
each end if you understand what I'm saying...

But please make sure that no UV light escapes the systems because it will
cause severe dammage to your eyes and skin (think severe sunburn / blindness
here...)

Glue the whole lot together, test for water tightnes and happy UV'ing
