Ben would most likely tell you go ahead and swim but just wear old suits. I'm a little more conservative and though it is probably fine, if it were my kids, I'd probably wait until it came down to under 20 (with a CYA of 60) and then wear an old suit that it won't matter if it fades.

By the way, no need to check everything every day when you aren't having problems. Just check chlorine and pH but if your chlorine is above 10ppm (with a Taylor kit), you'll need to dilute your water sample (half pool water and half distilled water mixed together) and then run the pH test with that.
