Some time reading pool school (multiple time) for a better understanding. You will probably have other questions after that.

But I will still help a little.

how many ounces should i add each night.
There is no each night figure, this all depends on many different factors. including but not limited to your CYA level, time in sun, covered, uncovered, used(by how many and how long). What your currect FC level is.

If your water is clear, your CC's are less than .5, and you pass an OCLT there is no need to shock. Shocking is not part of normal maintenance but is used to fight alage, organics, basically fix it when something goes wrong.
The only thing I can tell you is there is a lot of helpful information in pool school, and the pool calculator is very helpful to decide how much to add, as long as you know what levels your currently at and where you need to be.

Using the bottom of the pool calculator (effects of adding chemical) after entering your 5000 gallons at the top I can tell you that 1 Gallon of 10% bleach/liquid chlorine will raise your levels 20PPM. Using the FC column at the top just under where you enter your gallons, I can tell you it takes 7.5 oz of 8.25% bleach to raise FC levels 1PPM
