Cheap @$$ light?

[RichardB]

i have an old 4.5feet T8 light fixture. would it be any good on a 20g tank? would i kill corals using that? the bulbs are 32w and theres 2 in there.

i know...i'm cheap -_-

you might get away with some softies, ie..zoas, palys, shrooms... just get brand new bulbs.

What are their K ratings at? (i.e 14,000K)

Other than it being way too long, it should be ok.
You will probably want to change bulbs unless you know they are newish. Otherwise, they can cause problems.
