There's always a danger of introducing parasites into the DP when doing water change.

I was wondering if the long exposed UV lamps for Pond use be any good.

Tried using it in the DP for six hours and Chemo Therapied most of my fishes to death.

Bleached white the live rocks that had nice purple algae growth on it.

Pumping the tank water through UV shouldn't have such problem because the UV light is contain inside the container. You didn't expose the lamp right?

I dont think is necessary as the water will flow through your sump tank and the uv light.
