Remove the sand perches from the cage as they will rub and hurt your birds feet.
Instead look to get her some natural wooden perches, in different sized that will help exercise her feet, as well as keep the nails naturally trimmed.
If her nails are that long, you will likely have to trim them or take her to the vets. You have to be careful to only cut a small amount off.
If they are that bad, I think maybe a trip to the vets might be useful and you can ask for advise on trimming her nails in the future.
The following posts should help you with information about perches.
Plastic, sandpaper or wood
Also be weary of rope perches, as birds can ingest the fibers. I'd take some time to look at the forum and read the stickies. You'll likely find a load of information on things you thought were okay for your bird which aren't.
