Yes, if you want to use your refugium to attempt to control pH swings.

If it isnt on, does that defeat the purpose of the fuge ??
No, because pH stability isn't the one purpose of a refugium. Macroalgaes also provide phosphate scrubbing, and allow microorganisms a peaceful, seperage "refuge" to grow and mature before entering the main tank and becoming food.
