Default enough light?

i have a aqualight 72 watt light on my 20 gallon tank. this light has 2 36 watt bulbs, one is white the other looks almost like a black light. is this supposed to only be on at night? if so does that mean i really only have 36 watts on my plants? please help im worried everything is gonna die

The bulb that looks like a black light is probably an actinic bulb. These are designed for salt water tanks and will not be of much help in a planted tank. Some say they promote algae growth in a freshwater tank. You want to replace it with a daylight bulb. If these are compact flourescent bulbs (CFs), by the way, make sure the replacement bulb has the same pin configuration (straight or square) as the original bulbs. There's nothing wrong with starting out with using only the 36 watt bulb. That'll give you 1.8 watts per gallon to start out with, which should be ok for a lot of plants. Then when you add more plants, you can add the second bulb. Hope this helps.

Too much light will make the tank hard to balance out, and cause algae. I would start out with the one bulb, and work your way up to the second one when the tank is full of plants and co2 and ferts are all in order.

The blue bulb wont be of much help, in my opinion, and has always caused more algae for me.

Good luck with the tank!
