You can do them every day as long as they are rather small. It's hard to get replacement water properly mixed and the temp regulated that fast, but if you can do it then it wouldn't hurt to do small daily changes... By small I mean 2 or 3 percent. Not sure of the size of your tank...
That can be 21% a week, and until you get your trates back to an acceptible level, that's what I'd do.
If you don't have the means to do a daily then 5% every other day is OK also, as long as the temp matches (along with salinity of course).
That's be MHO
