    i have a 75 gal tank with 100lbs live rock. i also have a coralife aqualite pc with 260 watts (2- 10,000k and 2- 420nm bulbs). would i be able to keep most corals by just adding the two 70 watt fixtures or would it be best to go with the two 150's???

    Are you getting rid of your coralife fixture?
    If so, on a 75, I'd got with even bigger halides...

    get 150's, sometimes allitle cheaper than 70 watt bulbs and have 2x output, agreed with Matt, 140 or 300 watts is too little for a 75. maybe 2x 250 bulbs or even 400watt bulbs. Any actinic support?
