One nice thing about aging water is things evaporate from it, this includes both chlorine and ammonia gasses. In the days before chloranimes many fishkeepers did not use dechlor, they let new water sit out for a day or two before using it.
You are at the first 1/3 of a cycle or so and that means you are looking to add the second dose. The amount of ammonia left in the aged water you will add is not enough to matter. And you have ammonia bacteria working and reproducing. So the only danger is too much nitrite. This will not be an issue here, do the full 3 ppm addition when its time.
You can add the aged water once it has hit 24 hours. Wait maybe 30 minutes and you can test and, if the results come in at under .75 for ammonia and over 2.0 for nitrite add the 3 ppm.
You want to keep the tank as close to full as possible when adding ammonia during cycling, especially in smaller tanks. The reason is we are testing the concentration of ammonia in the water. If you have calculated a tank holds 10 gals. and using 9.5% ammonia to achieve 3 ppm requires 1.2 ml. be added If that tank is down 2 gallons, then you would be overdosing ammonia. If you change the above from 10 to 8 gallons, the ammonia dose drops from 1.2 to .96 ml. Save yourself more problems of having to estimate a dropped water level and then adjust dosing, just keep the tank topped up using the suggestions I made earlier.
