Please log in for more thread options I have a well planted good condition freshwater tropical 180 litre fish tank.
I am minded to fit a UV light switched on at night i.e. when the other lights
are off. I have a view that it would look good at night, however would it
harm the fish or plants ?
Any advice would be appreciated.

I found two things with UV tube (though don't run mine at night).
- It keeps algea down. After a year I get "hairy", replace tube and clears
up.
- Any plastic near UV tube ie reflector clips, live worm feeder etc "falls
to pieces" after a while, obviously being affected by the UV.
Oh the fish also look good as well.

Is this what is wrong with my tank I wonder?!? I posted a while back
regarding stringy weed on my plants, now ornaments etc. Is this the 'hairy'
you talk about? I have a Fluval Duo lid that has two tubes in, is it
possible the UV one has burnt out?

If you are looking to give a "night time" feel to your tank, you do not need
UV. What you need is one of the moon light effect bulbs available from your
LFS. Red lights apparently are supposed to give a better effect as it allows
fish to carry on normally as they can't see that colour, not sure where you
would get a red tube from though!
Under no circumstances should a UV be used unless enclosed within it's
supplied unit. UV light can and will cause damage to your eyes and cause
burns and other damage to your fish. UV's are sold for aquarium use, but the
bulbs are in a quartz sleeve and a purpose built unit to allow water to pass
through and kill pathogens.

An interesting idea, but probably not a good one, I'm afraid.
UV light can be very dangerous. If you look at it you could well blind
yourself; it probably wouldn't do your fish's eyesight a lot of good either.
You might be better off trying one of the blue tubes that are sold for
marine tanks. I suspect that would have roughly the effect you're
looking for but without the hazards associated with UV.
