I have a 15 gallon i put two 25 watts on it... is this okay?
And for some reason the light is yellow and looks rather weird....

Two 25 watt what? (That's a tongue twister... :roll: ) I'm assuming you mean fluorescents. It depends what kind of bulbs/tubes are in the fixture as for the color they are going to look in your tank.

Anyway, that gives you over 3 watts/gallon, so it will give you quite a few options.

Its 2 light bulbs (25 watts each), since my lighting system is rather old... (8 to 9 years old)

Is 3 watts per gallon good? Thats what i was going for...

 

[SnyperP]

what type of light is it? It really makes a difference.

 

[trenac]

bulb/light colors
10,000k-white or bluish tint
5000k-yellow
6700k-between the above two

Yes, 3WPG is good...But with smaller tanks the WPG rule breaks down a bit. Read this: http://www.rexgrigg.com/mlt.htm

Do you plan on adding C02?

 

[turtlehead]

is his light incandescent or flourescent?

 

[Black oranda]

Incandescent light bulb im guessing, Im starting to understand the wpg rule,
Hmm if it will be good to add co2 of course ill try and get my hands on it.
Lighting seems somewhat confusing...

Thanks everyone.

If it's incandescent it won't do much of anything for plants no matter how many watts you have, except maybe fry them from the heat.
If you don't want to buy a new strip with fluorescent tubes in it, you should at least try to get some of the screw-in CF lights you can get for around $5 ea. at almost any store. That will boost your lighting a lot going from incandescent to fluorescent.

ill look for the fluorescent bulbs....
