UV in a 4x2x2

[grumpyguy]

Hi all.

I'm looking to get a uv to put on my moderately planted 4x2. How big of a unit do I need? Just want to polish the water and mainly keep the algae at bay. Would a small internal that I could swap between tanks be enough or a pump driven one be the only way to go?

thanks
scott.

the small internal UV jobbies have thier place but not in a 4x2x2 tank. go pondmaster or good quality UV. The Danes have a nice looking unit, debarry and eheim is comming out with one at some stage, but rest assured it is going to cost a pretty penny!

I bought a De Bary 15E watt UVS about 2 years ago from SeaMe.com for $300. It is a quality product.
