question about lighting
- I have a 20 gallon high tank that is my first attempt at this great
hobby. The problem I am facing is that I don't like the light that came
with my lid. My friend that I use to know used lights that put off a
blue light and it made his aquarium look much better, with brighter
colors of the fish and decor. I was wondering if anyone knows what kind
of bulb that would be?

Tank is about 24-inches long and the next size up in fluorescent
lighting is usually a 24" 20W lamp, but that probably wouldn't fit
due to no room to spare, so I assume a 15W/18" lamp.

usually related to "grolux" (aka Plant and Aquarium) lamps. These
tend to be heavy in the blue and red so you often get a pinkish or
purplish look. Looks great on fish like neons and cardinal tetras for
example, but to our eyes they also tend to look a little dim (we see
best in the middle of the visible spectrum so green/yellow area).

marked on the packaging, you want to go with something in the 5000K-
6700K range which is considered a "daylight" range. If you don't want
to buy aquarium specialty lamps, those that are marked for the
aquarium industry, there are many choices in normal lamps you can
investigate at places like Home Depot, Lowes, your local hardware
store, etc. For example the GE Chroma50 is a 5000K lamp often marked
as a "Sunshine" lamp at Home Depot. I think it comes in a bright
orange cardboard wrapper. This one is pretty good. There is a Philips
one, called Ultra daylight or something like that which tend to be a
bit less yellow and more bluish that is also very good, although I
seem to recall it usually is never available in the 18" length but
always lots of them in the 4-foot (40W) length, so you might have
trouble with that one. Basically look for the lamps that are marked
as Daylight, Ultra, and sunshine type lamps which tend to try and
give a more natural light output.
If that doesn't work, there are a huge number of aquarium lamps you
can try. Many of them tend to have spectrum graphs printed on the
wrapper to help just how the light will look. Triton lamps, for
example, look very nice, but expect to pay about 3x (~$15+) for these
type of lamps compared to about $5 for something like a GE "Sunshine"
lamp at Home Depot.
