Dosing whilst on vacation

[Pennywise the Clown]

At the moment I am manually dosing 10ml of Seachem Fusion 2 a day. I am away on vacation for 7 days from Sunday. My daughter is on feeding duty but I want to make things as easy as possible for her.
I have an ATO container that holds enough water for the duration. Can I just add 70ml of Fusion into the container before I go away and just let the ATO dose my tank?

Potentially, but I wouldn't go that route. If the daughter is on feeding detail, maybe have her do the dose as well. 10ml is exactly one syringe full, so... Easy peasy.
Just make sure to go over the details before you head out of town. I always make it a point to make a daily checklist for whomever is tank sitting. That way nothing is forgotten.
I also pre-portion the food. No guessing or (but they were still hungry) questions about how much to feed.
Lastly, know that your fish can go much longer than a week or so without being fed.. they won't like it, but they will be fine nonetheless...
