I'd just work on getting your skimmer dialed in. If your GF is not as in to your tank as you are it's kind if difficult to have someone else look after your hobby with the added pressure of dosing. Plus it's not really fair. Try running a phosphate reactor. Is your algae fuzzy or look kind of like a fern plant? If it looks like fern it's bryopsis.
