What type of lighting?

[Tarolisol]

I am getting a 18x18x18 cube tank and wondering how i should go about lighting it. I want to keep mainly zoos and ricordia.

My 24x18x18 has mainly zoos. I have been lighting it with one 175W MH, however, I am not happy with that, as some of my zoos are doing less than perfect. I have changed to one 24W T5 daylight, and one 28W actinic PC. To my eyes the zoos are doing better. I have ordered a 65W 460/420 nm bulb, so when it gets here I am going to give my 2X65W PC fixture another go.
My preliminary advice is then "don't use halides in a tank that size if you are doing mainly zoanthids" :mrgreen:

Yeah i wanted to try and stay away from halides for this tank, but what kind of lights are made 18" long, PC? T5? and where can i get them?

I have some 28W PC's that are less than 18" long. I believe there is a 96W PC tube that is also less than 18" long. You might have a look at J&L for lighting. Other online merchants also will have what you are looking for. :eek:
