Hopefully, I don't ruffle too many feathers here, but I think your SLAM is over, and you should let your FC levels drift down into normal range, so that you can finish balancing the water (and go swimming with the 2 year old). Here's why...
PH is a critical component in determining your calcite saturation index (CSI) which can affect water clarity negatively - the symptoms of it being too high can be cloudy water. During a SLAM, people sometimes get so caught up with the FC and CC levels that they seem to forget that balanced, clear water is the ultimate goal.
As Kim and I stated earlier, you cannot get accurate PH levels when testing at high FC levels. I guess what I'm saying is, you still need to balance the water, and you can't do it with FC levels being that high. Also, while the little guy SHOULD be safe to swim in FC levels less than the SLAM level for you CYA, those levels are based on the science discussed here on the forum - not everyone else in the world agrees. For example, Costa Contra County's health department prohibits swimming in public pools with FC levels over 10ppm even with CYA levels up to 100ppm. I have a two year old and I've never tried to pull off an effective SLAM AND let daughter swim at the same time.
The problem with the third (and often final) test to end a SLAM is that it is subjective. Unlike the OCLT and CC tests, it can be based on opinion. My opinion is that, if you pass the OCLT, your CC level is .5 or under, and you can tell if a coin is face up or face down on the bottom of a 54" pool, you're done. Time to let the FC level drop and balance the water while continuing to filter out the particulates.
Anyway, it's ultimately up to you. If it were me, I'd keep filtering, let the FC level drop, run another panel of tests, verify your CH level and adjust your TA, PH, and CYA levels accordingly.
Either way, I'll think you'll be ok. Just my two cents.
