If you do water changes twice every day, as you say, she should be fine. If you wanted to make less effort you could put her jar underneath the output of the filter (provided it isn't too strong) and have it going in her jar and then overflowing into the tank, so she effectively shares the same water as the rest of the tank.
Let us know how it goes! My males are totally slack with building bubble nests, even though they have one or more females with them. Maybe it's because they're both in community tank type setups and not 'private' ones.
