Its a sterilizer. Technically doesnt kill any of them (well, i am sure it kills SOME). It sterilizes them and prevents them from reproducing. All sterilizers work generally the same. Yes, some are better than others but if you are looking for a Sterlizer under $100 bucks, there are only a couple of other options out there. The bigger issue is home much contact time does the water have with the UV radiation. I have a larger one that I bought on my nano and it is over kill. But that one was more expensive. I didnt like it because i had to plumb it where as the one above..i just put directly in my fuge.
Less than 100 is a tough find for anything you won't end up replacing in a year. I tried the Jup @NJTaxMan has ( not knocking ya if it works for you then great) and it busted on me twice, after getting the replacement. I have had 2 Coralife Turbo Twist before that one, each lasting 10 years. And have now purchased a third. You'd be looking at about just under 200 bucks plus a small pump at probably 40 bucks. I just wouldn't cheap out here. I've battled Dinos and Cyano once each, each time the UV was the workhorse that solved it. Best of luck.
Just saw this lol....there it is. Buy it OP.
Yup. I like it...the only complaint i had was having to replumb. Outside of that..nothing but good things about this.
