leaving a reef for two weeks will probably be a total disaster unless you have all the fancy automated gear and backups to take that vacation but even then,,,,poof
I have a full Neptune system and I would be fairly reluctant to leave it for 2 weeks. Something seems to go wrong every time I go away. Usually a sensor fails or get some strange number. Maybe in looking at the app more than I normally do.
I would try get someone to check in on it. Ideally local fish shop.
I hire professional help, as I don't have anyone nearby I trust enough with SW tanks. I have 5 cameras, Hydros and my own backend for more advanced monitoring, but I still have them come by every other day to visually check everything is OK. Never trust, always verify.
