lighting question
My guppy tank lightbulb blew out last night. I went to Wal-Mart and grabbed a set of 2 15w bulbs. They also had 25w bulbs and I wasn't sure what watt mine was so I had to check some of the tank they sell. Some tanks said they included 15w, some said they included 25w. Does the watt difference really matter? I went wth 15w because they're cheaper actually, but could I have gone with 25, or would that be too bright? My tank is about 5g's or so. Just has the 3 guppies and a snail, all happy now without dying and I've replaced the filter too

15W bulbs are fine. You may want to have the brighter bulbs if you are growing plants and such but remember brighter lights grow algae as well

The 25 watt lights would of been fine. But so is the 15 watt for a tank that small. You just have to be carfull that your not getting a lot of the red spectrum in the light. Which is what promotes algae growth. There should be a spectrum chart on the side of the box the light comes in that will show you how its designed.

I was at superstore today and they had 23 watt PC's in a daylight (6500K) for about 5 bucks each. they screw into regular sockets for light bulbs and would work perfect for fresh water tanks.

The cheapest I have seen for screw in PCs is at RONA. I picked up a box of 6 23 watt bulbs for $16 on sale.......they also had some 23 watt PC "grow lights" that had colour temps that would be really nice on a fresh water set up!!
