Works as described "Freshwater"
September 9, 2013
Well some people don't' agree that freshwater tanks need UV "protection" but I did it anyways just for peace of mind. My water was clear before and is still clear but what I like about this unit is that it is all self contained, couldn't be easier to setup and has a variable water flow adjustment. Also it's quite and I didn't notice any increase what so ever. My fish seem to enjoy the extra flow too. In short, not disappointed and as said before, I have a little better peace of mind about having it in my freshwater tank..
Pros:Quite, self-contained, just plug and play.
