Lighting and UV

[bizkit]

I have been wanting a UV for my 20g long reef. What size and flow rate should I go with. Also I have a 55 watt PC light on there now is there any upgrade in lights I should go with? Money is not an issue so please let me know what you think.

re: the UV
I'm not sure on a tank that size...probably a 4watt. What you're looking for is an exposure of 60,000 µw/cm2, and a flowrate of about 120gph. I'm not sure what gives you that combo. The people at <a href="http://www.aquaultraviolet.com/" target="_blank">http://www.aquaultraviolet.com</a> could probably tell you better thanI can- they seem to know their stuff and actually answer the phone.
