Reply With QuoteWell, I would say it's a good thing to have but not necessary a must have. It's good for controlling algae in a tank environment. Then again usage is only to a bare minimum. Point to note, it eradicates all kinds of bacteria whether good or bad.
did a search for uv light .. turns out nothing
Anyone using uv to control the algae in their planted tank..
what the outcome and benefit?

Something about the water & the fishes that calms me down.
anything others thing to note when installing one...
any of forumer presently using it? thinking of installing one.. after all my previous tank setup was overrun by BGA.. my new setup started to show sign of BGA again...

I have a UV filtration unit, from my old tank, I used it once a week to clear some bacterias from my tank, running for at least 4 hrs max.
Dun think it controls algea growth, kills bacteria only.

Summary:
1) To retain the beneficial bacteria in your filter, connect UV sterilser to outflow of filter and not the inflow.
2) The UV light tube needs to be replaced between 6 to 12 months for the sterilising effect to be maintained.
3) The glass surfaces of the steriliser may need to be cleaned regularly.
4) The steriliser must be switched on for its effect to take place.
I think UV is only good against greenwater.
I was running UV filtration on both planted and bare tanks, and both tanks were still visited by hair algae and brown alage.
It will kill anything that could pass through.... I thinkOriginally Posted by evolim83
thankx.. will it kill BGA ... since it is a bacteria and algae..
will it affect the fertilizer u added into the tank? dont wann the UV to break the fertilizer into harmful stuff..

The UVC light "kills" most micro-organisms if the energy density is high enough to cause damage to the DNA. The light also has the potential to create oxidising free radicals that gives it (the light) its sterilising property.
For algae, the free floating form will be "killed"; therefore, it is very effective for "green water" algae. For other forms of surface algae (e.g. green film/slime algae, hair algae etc.), UVC light will limit the spread but not totally eliminate all such algae.
As for fertilised sand base, even the grandmaster (Takeshi Amano) is using a UVC [see the latest ADA 2006 catalogue] light to limit the algae growth in one of his demo tank. As long as the UVC light is positioned AFTER the filter, the water chemistry should not change significantly.
Hi, I'm new here. Just wanted to say that UV sterilizers does breaks down the liquid fertilizers quickly, esp fe. However it should not break down everything, typically ion trace elements. UV is good but it only kills whatever the passes through the light... Ever thought of the O3 sterilizer? Apparently more effective but UVS with enhanced with quartz bulbs are more than sufficient. The UVS or UVC should always be left running for optimum results. UVS kills parasites when it is in its floating stage but it does not "cure" fishes. To control other algae like hair or brown, I would suggest investing in some ottocinclus and SAEs. SAEs are the only known fish to consume brown algae.
I've been using the UV lamp for several years in my planted tank and so far I'm satisfied in helping me to :
1. Control the algae growth specially in early weeks after setup / renovation
2. Keep the water crystal clear
3. Keep the water free from harmful bacteria specially when we do regular water change
4. Keep the fish, shrimp and snails free from bacterial sickness attack
5. Reduce the solved Fe when your water source identified as 'higher in Fe' content level
To make the operation simple, I just join the operation time along with the tank lamps using the timer
So you actually on the UVC during the photo period? I have one running for my pleco tank, for 8 hrs a day. Not sure if this is good enough to clear the tank of any harmful pathogens / bacteria. The instruction mentioned different flowrate will kill different harmful organisms such as pathogens, bacterias or others.
May I ask what flowrate your running for your UVC? For mine, I'm using my eheim2028 to drive it.
i am using my turbotwist uvc filter 9W power on my 2ft tank so far so good didnt have any green invasion and water remail crystal clear most of the time
