Easy question from the newbie ... should I SLAM my pool periodically even though my levels are good and the water is crystal clear? Or, should I only SLAM if I NEED to ?
Thanks!

Good Idea To SLAM Periodically ??

Only SLAM if you need to. If you manage your water parameters the TFP way, with emphasis on the FC/CYA relationship. You should never need to slam it.
Do you take Tums even if your stomach is not burning?
My plan is to go without ever SLAMming by paying attention to my FC, pH and CYA.

If your water is clean and clear then a periodic SLAM makes no sense. You would simply be raising you pool water up to shock level and passing the overnight chlorine loss criterion right away. It would simply be a waste of bleach which would add unnecessary amounts of salt and lye to your pool water. You would also use more acid since a SLAM requires a drop in pH first. It's really nothing more than a waste of money, time and testing reagents.

Ten years now, never have Shocked or SLAMed my pool. It is a treatment for a problem. If you don't have the problem, you don't need the treatment
Never SLAM but do run a OCLT about every other week in the summer just to make sure there is nothing hiding. I have always passed so may not even need to do it BUT it makes me feel good so..........LOL

Just test and maintain. There will hopefully never be a need to SLAM. I haven't done one since switching to the TFP method.
Oops! Sounds like a bit of pool store lore still hanging around, Bruce! Hang tough...fight it...soon it'll be a distant memory.... 
The OCLT is a great indicator. Do it periodically if something seems off. I will sometimes go to 15% of the cya if I suspect a risk of algae.
.
There is debate about whether the OCLT is accurate at lower than shock level FC.... Just saying.
If you do an OCLT at maintenance levels, be sure to use the 25ml sample for greater accuracy.
