Thanks, all. I actually did take care of the pool myself for five years. But I hit some physical challenges and my job got busier, so I hired someone. Yes, he was using both liquid chlorine and tabs together. Ugh. Looks like it's time for me to take it back over.
Assuming the standard weekly visit, even with a conscientious pool guy, a pool owner shouldn't really think that they don't have to do anything pool ever. Though that is the common misconception.
Even with an SWG, and certainly without one, a week is too long a span of time to ignore a pool. For example, I have an SWG and I generally maintain my pool only once a week, but during swim season I try to check on the pool once a day. I call it a "drive by." I can check that my pump is working, that its basket isn't full, that the filter is OK, that the water is pumping, that my SWG is happy, that my skimmer isn't clogged up and that my vacuum is doing its job, all in the time it takes me to walk around my pool (about 30 seconds). And that's a nice way to start (or end) a work day.
Otherwise, any number of things could go wrong that I don't want a week to go by without knowing about. Dead pump? Clogged filter? Leaking pipes? Etc, etc. Those things (and a lot more) can happen any minute of any day. For example, I found a dead squirrel in my skimmer basket today. Left unnoticed, the idea of my kids swimming in dead squirrel leavings everyday for a week is pretty sickening. That wouldn't be a pool guy's fault (or responsibility), nor equipment failure, just bad luck.
More to the point, if you can't fully maintain a pool yourself, for whatever reason, you should be able to work out a compromise with a pool guy. Do a 30-second "drive by" as often as possible, maybe check your FC and pH halfway between the pool guy's visits, but let him do everything else. You manage the maintenance protocols he is to provide (like "no pucks", for example, or desired pH and FC levels, etc), but he does the bulk of the grunt work (brushing and filter cleaning, lugging chlorine, whatever you don't want to do).
You end up doing way less work than if you had to do everything, but the pool is still being maintained as per your standards (TFP standards). The trick is finding the right guy that will take direction and be able to let go the ego of thinking only his way is the right way. It doesn't have to be all you, or all pool guy, there could be a happy medium.
Just know, no matter how much you automate, or whether you have the best pool guy ever, you'll still have
some unavoidable responsibilities if you want a clean and safe pool.
