Barracuda Posted May 15, 2009 Share Posted May 15, 2009 Hi all, thinking of getting a UV sterilizer in my tank to get rid of algae/parasites/other bad stuff (like white spot). I dont know much about it so i need some advice First of all, what is the difference between a UV and a UV-C? I am looking at these from GuppiesAquariumProducts.com.au http://www.guppysaquariumproducts.com.au/u...ts/prod_37.html (UV-C) http://www.guppysaquariumproducts.com.au/u...r/prod_342.html (UV) The UV one (second link) is a "self contained UV filter" - what does this mean? Is it a UV steralizer inside a hang on filter? What sort of specs should I be looking at? I think the UV-C is 9watt, flowrate 800l/h. The UV "Self contained filter" is 5W (i think - power head?, and 500l/h flow rate. It will be for a 6 foot, 300L tank that currently has a fluval 405 filter (1300lph). Will either of these two uv's be suitable? Which one do you reckon is better? Thanks for your all the help Link to comment Share on other sites More sharing options...
ant265 Posted May 16, 2009 Share Posted May 16, 2009 You dont need a UV to get rid of whitespot there are medications for it. As for the links the UV-C i think is better. The other one doesnt say much at all about the unit, the wattage is the powerhead not the light strength i believe. Wait for other opinions and maybe research more in the meantime HTH Link to comment Share on other sites More sharing options...

Not a hang on, they are both internal filters with UV light inside them so wouldnt have much filtration media id imagine Link to comment Share on other sites More sharing options...
Barracuda Posted May 16, 2009 Author Share Posted May 16, 2009 Ok thanks...by the way, I have always wondered whats the diff between hang on and internal? Link to comment Share on other sites More sharing options...
gianniz Posted May 17, 2009 Share Posted May 17, 2009 i have canister uv filter. all the reviews says internal ones are crap. the most important thing you need to know is the time the water is in contact with the light. approx 2-3 seconds will kill most badies including whitespots. i definitely think its worth the money but mines one of those expensive brand. haven't tried the cheaper ones but as i said before, make sure the unit has a large canister.
