What filter?
You definately need to rate it higher in EI (Exposure Index) than 
with daylight, at least with a predominance of tungsten lights 
(instead of fluorescent, which contains very little IR).

Assuming #25 red filter, and outboard light meter, start with 100 or 
200 ASA, instead of the daylight rating of 50ASA.

If you use an inboard light meter, and measure TTL & TTF (through the 
filter), then you might not have to correct your usual 
daylight-rating much, simply because the light meter will see the 
predominance of red tones.
