NO chlorine

You also won't find much clarifier use here either.

But again, mostly because the pools around here tend not to need it.

You can look at regular (weekly, usually) PolyQuat algaecide use as insurance. It costs extra and really isn't needed if you properly maintain your Free Chlorine (FC) level relative to your Cyanuric Acid (CYA) level. However, if you fear letting the chlorine get too low and want some protection against algae growth, then an algaecide is one way to do that. Another would be to use 50 ppm Borates in the pool. Again, not necessary items and are extra expense, but are options nevertheless. Most people here don't bother with algaecides, clarifiers, weekly shocking and the like, but it's your pool and only you can decide the cost/convenience/insurance sorts of tradeoffs.
