When your res starts to get low, just top it off with water and adjust the ph level untill its time to change the entire reservoir (usually every 10-14 days)
 
I think both methods are correct.
"top off with water and change entire reservoir routinely/weekly"
or
"top off with solution and monitor ph/ppm"

It truly depends on what you want to do and what is convenient for your setup.
Sometimes its more convenient to change then entire reservoir than to monitor the ph/ppm. (single site usually)
Sometimes its way more convenient to monitor the reservoir and not bother changing it. (multi site usually)
I personally like to wipe down the reservoir. Possibly keep two reservoirs handy if they are trash cans or rubbermaids. So that you can have a clean one ready when you change the res.

Edit: Just realized you were referring to aero system. Go with what tat2ue mentioned, "top off with water, change bi-weekly"
 
I myself keep my tank full and find I am adding about four gallons every five days or so. I use nothing but a PPM meter. Two things make me change out my tanks. One if the water looks brackish and if the PPM meter starts reading erratically and won't zero in on a reading of say 225. So far it has been two to three months between changes. My tank is a 20 gallon and has 15 gallons most the time. Pumps running 24/7. You can see my system at myaeroponics
