You would need to find out what kid of LEDs he is using. 1000W doesn't sound anything close to what is correct and wattage per foot of tank doesn't not really apply to LED since some LEDs are extremely inefficient and some are exceptionally good. It all depends on the size of your tank too. The color output for growing vegetables is also completely different, its more of a red color than the 14000K mixture you want for a coral tank.
For 3 foot tank we recommend 48 LEDs based on an 18inch wide tank and approximately 24inches deep. That will consume approximately 144 watts. Using Cree XP-Es that is more output than you will need and usually people attach a dimmer and have them dimmed down a little. If your tank is deeper or wider you can add more.
Hope that helps.
