Assuming that is true, how clean does it have to be? I've seen a lot of residential pools and they all had nice sparkling clean water and none were running anywhere close to 24/7.
I have a pool that is 45 x 20, plus an extra shallow section, 48,000 gallons, with a DE filter and it stays clean with 6 hours of circulation. The rule of thumb is that it should turn over the water about once a day. Running it 6 hours probably does about half that, but it works with no problems for me.
It is desirable to run it more when it's heavily used, but I've seen plenty of pools with families with kinds and again, none were running close to 24/7. As for the algae, might be cheaper to use an algaecide than pay for $120 a month in extra electricity, no?
Installed or for the box? You can get an Intermatic on the internet for $100. And quickly paid for if you cut the running time in half. After that, you're way ahead. Running that pump full time costs about $200 a month assuming your electric is about .15 cents per kwh.
Maybe others with pools would care to comment.

I agree it should have a switch. And as I said, I'd be suspicous of the hack who installed it without one. I'd check the wiring, particularly the grounding and bonding.
