guys what gets hotter VHO
or Metal halides?
reason i ask is because i have a all on one system it currently has 3 lighting fixtures to suit std flouecent (spelling) which has 1 Actinic Blue, 1 50/50, 1 white However as you could imagine its not enough, all though the heat is minimal which is great.
another question now
should I just add another 2 std Fluorescent, blue and white, whould this be substancial? or should i bite the bullet and get VHO
's? Metal halides i think may be to hard to creat into my fixture, but if they run alot lesser temprature i will have to find a way i suppose.
by the way the tank is reef.
