I am setting up a 4 ft tank and i am trying to decide on lighting and am a little confused with what to go with. a friend tells me to go with vho but when reading on this site it said vho was old technology. i know metal halides are probably the way to go but a little to expensive for me right now. like i said i am setting up a 4 ft tank but will be moving to a 6ft after a while so i need my stuff to be able to transfer. i thought maybe an icecap 660 can powr 4 - 4ft bulbs right now 3 white 1 atinic and have a cheap power compact that will click on atinics an hour earlier. when i switch to a 6ft i can use the 660 to power 2 atinics and buy 3 metal halides. what does that sound like to you guys.
