Which UV sterilizer?

[RaeRae]

I'm going to purchase a UV sterilizer today. I'm either going with the sun sun 5 watt or the jbj nano zap. The sun sun just plugs in and sits in the back of your chamber. The jbj hooks in line with your return pump period has anyone had any luck with either one of these?

Both a waste of money IMO.
for small tanks like an AIO, a UV filter isnt effective or needed. save that money for corals
