Flourescent Question

Those are perfectly fine for a inexpensive solution. They will provide much much more light output than an incandescent bulb will.
 
there aren't fish in there as of yet. i'm going to have salvinia covering the surface, and my reflectors aren't exactly high quality. i really don't think it should be too bad for the fishes. though it was bright with 10 watts pc...
 
I've been using those bulbs for months in my 20 gal out-grow tanks-3 each- for my baby Gold Gouramis. The color isn't the greatest, but the corkscrew and cambomba grow like crazy. I also used one in my 5 gal tank when they were tiny fry, but used some black window screen material to cut down on the light. HTH Steve
 
Congrats on finding a relatively cheap and easy solution to lighting up a tank! But here are some things I've learned along the way! First is that there are quite a few bulbs out there... not are bulbs are equal! The local Home Depot carries several kind and most are considered 'soft white' and tose are the lower temp rating and somewhat yellow looking bulbs. I then found another brand that were considered 'daylight' bulbs and those are much better! They are rated at 6,500 K temp, come in several different wattages and are like $7 ea. I'm using them on two different 20 gallon planted tanks and really like the look. They have a crisp, cool look that really seems to bring colors out and plants grow great with these!

Good luck
