OK. Have a safe trip.

we'll be here for you when you get back.
5 ppm a day will hopefully be like hitting the pause button. If your dosing needs were fairly consistent, I'd personally have her add as you were doing. There is assumed risk involved, just to be totally clear. (Bleached liner) But with green water, the FC should be down by the next dog feeding time. The next 4 days will likely behave as the last without frequent dosing.
We just helped someone who's schedule was not helpful for SLAM. It took him over two weeks to get to the part that most have in two days. The process works even when it's slow due to other commitments.
