My UV is of a design that the water flows extremely close to the bulb.
The design is made to sterilize the water as it goes through it. Mine
is 8 watt and has a protective quartz sleeve to prevent cool water from
breaking the bulb. I mean the water flows right past the bulb inside a
PVC tube.

Sounds like you have a sunlamp...which will be interesting in seeing if
it does squat....
good luck...

Knowing the cause isn't all that important, the first thing to do is
eliminate the algae, then bring all your nutrient levels back into
proper ranges...but first get rid of the algae. Here's a webpage
that
describes five fairly easy and/or quick methods to remove green
water.
