I disagree i used have problems with algae now i dont since installing the Uv, using the same lights..
Do you really need a UV sterilizer on Large tank?

But it's not an essential peice of kit you don't need it !!!
With a good filter and frequent water changes you can control your algea problems and cloudy water.

That is the key. If you had a problem, like green water, then they are beneficial becuase that is what they are primarily used for. If your tank is not having any issues, water is clear etc, then there is no benefit to having one IMO.
let's make it clear... some of us have opinions that it doesn't kill beneficial bacteria since it is in our bio-balls or what so ever we have... but to think of it, we test water for nitrates (which are beneficial bacteria) right? so that means our water has bacteria since the water test can detect it... now since it is also in the water which i presume... it will reduce in quantity since it passes through the UV light... hope i got it right. haven't had a UV, but still having second thought.. not because of the $$$ but if it is really going to help eradicate most of the pathogens and problems in the aquarium. one more thing... long exposure to UV light will contribute to sterility in males... but since it's protected in a capsule don't worry about it..just a share of though.

There you have it! If you don't want to clean your tank as much It is a good idea!
It's not needed but it made my tank very clear.

Dan you're wrong about that in bad cases.
The water here in Spain is terrible, you fill a tank up from scratch and the water is cloudy. The bad water combined with a bit of direct light led to my tank being really really cloudy, like a white/green cloudyness. Partly bad water, partly algae particles and some algae bits growing on the glass.
Now stotty kindly sent me a UV, and a few days later my tank is crystal clear, completely clear.
The tank is a 180 and I could not even see the other side of the tank lengthways, that's how bad it is.
And about what you were saying of good filtration and water changes, it's very well filtered. 2 eheim canisters, 2 internal filters and a backup sponge filter/airpump. And yet even with large water changes the tank was always cloudy.
The UV made it crystal clear in a few days and it's stayed that way since, so in some cases they really are an essential piece of kit. There aren't even any algae bits on the glass now.

hahaha, no nitrates are not beneficial bacteria, nitrates are bad, you're aiming to have low nitrates, that's the point of water changes.
Like I said, all the beneficial bacteria colonizes in the filter media, and on some surfaces in the tank like sand and rocks. Not in the water itself.
So like I said, it's impossible for a UV to destroy the bacteria, as it does not come into contact with it.

Well in your case you need one but a large percentage of people don't need it so i'll meet you half way and say that in some cases people may need them but they are not essential to everyone.
Also you live in spain ? nice where abouts ? my mother in law lives out there in mercia it think thats how you spell it, It's just outside ala canti another wrong spelling i think.
