very effective against waterborne algae
October 5, 2013
After setting up my planted 35H tank I was battling some green water. A little over 2 days with the uv-3 and it's all clear. For the price this unit is hard to beat. I didn't purchase the matching powerhead from truAqua, and thus it took quite a bit of fiddling to get a good connection and stable position in the tank. YMMV on that aspect. The cord placement could possibly be refined and possibly a less stiff cord provided. It would also be quite nice if the unit could be 'convertible' for in-line use.
Pros:Effective, inexpensive, well made
Cons:somewhat bulky, not easily convertible for in-line use.
