    I'm going through some aquarium stuff my brother in law has and I've decided to put a 20 gallon tank up, but I don't know what kind of light. It's going. To be a tropical tank so should I use a blue light or not?

    You want something that is going to look good on your fish, so something in the 5000K to 7000K color temperature range. If you have plants, go for about 6500K :)
