Running Ati t5 without bulb

[Albz]

Hey reefers, quick question. I have a ATI T5 4bulb fixture, and id like to only use 3 bulbs in the fixture. So my question is, the forth slot, can i leave it without a bulb and still run the fixture?

Nope. You have to complete the circuit for the ballasts to work
