Converting a saltwater tank to freshwater Lighting

Do I Need different Flourescent light bulbs when I convert?

No you dont need new lighting for freshwater. and acrylic lighting? i dont know what that is i think clownfishrocks was refering to actinic lights which isnt necessary for freshwater but if you have them it is fine. It will make the tank look much nicer but, will only benefit you with a planted freshwater aquarium but wont hurt by any means.

but i advise you get an acrylic light they are the bomb
