Sparkling clean does not mean that a pool is sanitary. "Frog" may keep algae away but won't kill viruses.

SWCGs are easy but are not economical.

I think Dave's suggestion is a good one. A way you could get around having to check it daily would be to deliberately run a high CYA high chlorine pool. Check out the Best Guess Chlorine Chart in my signature below to learn about the relationship between CYA and needed chlorine levels. For pools with high CYA, sometimes you can get away with adding bleach a couple times a week instead of daily. Just another option for you to think about.
