Don't feel to bad about the PhosFree while you don't NEED if you maintain proper FC all the time it MIGHT buy you some time in the event you don't
I'm not advocating for it's use (though I use it). But life happens sometimes and I neglect the pool so I think of it like a little backup
I also use (have used) trichlor, dichlor, calhypo, polyquat, clarifier and floc from time to time. The key is I tell the pool store what I need/want and not the other way around
Learn your pool and enjoy it. This is definitely the right place to do it! Almost swim time in Texas
