Uv On Fresh Water Aquarium

[Rainbow4]

Hi going through a bacteria bloom at the moment which is getting on my nerves my tank has been running
For about 3 months all has been good with no ammonia and nitrite problems since it was cycled and not overstocked ,water has been crystal clear until a couple of weeks ago when it went cloudy not a green cloud but light white cloudiness only feeding once a day, planted with amozon sword and was planted with
Twisted vallis but have removed it as it kept melting as i thought it could be adding to the problem with organic matter checked filter which is pretty clean rinsed sponges in aquarium water and put back together, was wondering would a uv help my problem. Any advise would be appreciated.
Thanks.

I was going through the exact same thing running a 100g Discus tank. Doing 2x25% water changes a week the tank seemed to be in a permanent state of bloom. I did a lot of research on UV sterilizers  and found there are a lot of cheap poor quality products on the market (mainly Chinese imports) that are a complete waste of money. I decided on a V2 Vecton 600 for up to 130g tanks and I haven't looked back. I am really pleased with the results which happened literally overnight. I would say go for it, they are not that expensive £82 inc delivery (less for smaller tanks). All I would add is go for a slightly larger unit rather than one too small for your setup.

+1 for Vecton, top quality UV.
 
Just make sure you find out your flow rate before purchasing.  You filter should have this in the manual or the manufacturer should list this online.  If your flow rate is too high the UV will be ineffective.  A Vecton 200 isn't necessarily suited to a 200 litre tank for example if your flow rate is 1300lph.
 
UV filtration will cut down on any free floating algae blooms and free floating pathogens.  
 
For reference, if you're fully cycled UV is fine but I'd not run UV if a tank is still cycling.  
 
Just make sure you get yourself some hose clips from a DIY store if you do go for a Vecton.  I'm never convinced that filter hosing would stay put under pressure without them.

Although you could invest in a UV sterilizer, you gotta wonder about the root cause. I mean if you've had crystal clear water right along and didn't overfeed, why the bloom? Are you doing sufficient partial water changes?
Are you servicing the filter(s) enough? Do you have detritus down in the gravel? Is it a planted tank? How are your nitrates?
In situations like this, I always ask myself what's changed to cause this effect?...and in this case, adding a UV sterilizer may compensate for the problem externally when you might be better served finding the root cause.
In any case, good luck and I hope you get it resolved.

Melting plants could indicate a nutrient deficiency that could be affecting plants and algae only but not bacteria.  You might want to try a good trace fertilizer.

Fitted a vecton 300uv to my tank vast improvement over night ,the clarity gets better every day its great to see the fish properly without looking through a haze,worth spending £76 on a uv, obviously will carry on with proper tank maintenance as you do.

Had my uv on my tank for a couple of weeks now the clarity is amazing it looks like there is no water in the tank these vecton uvs
Are pretty good .
