Intex 16x48 Ultra Frame Pool

[PoolDoc]

The proper level is a range, not a specific number. It's better to be high than low.

If you are following the SSR, you will gradually build up a stabilizer residual that will reduce loss to sunlight.

But, you can NOT reduce loss to people 'goo'. People 'goo' includes of sweat, skin cells, fecal residue, and skin oils. The only way to reduce those is to not swim. But people 'goo' also includes lotion, sunscreen, and urine. Avoiding lotion use just prior to pool use will help, as will being careful not to use excess sunscreen. (Of course, you don't want to fail to get adequate coverage.) Urine is the major element in people 'goo' that CAN be reduced or eliminated. Steps that work include:

+ requiring that everyone 'potty' BEFORE entering the pool.
+ declaring an hourly potty break.
+ having an outdoor chemical toilet, like this

Stansport Cabana Privacy Shelter Tent (cheap, but people found it hard to assemble!)
Cleanwaste Portable Privacy Tent (easy to set up)

Reliance Products Portable Toilet
Camco 41541 Portable Toilet

+ have a designated 'pee' tree.
+ etc.

Urine consumes a LOT of chlorine and most people pee in the pool, under some conditions. *ALL* serious competitive swimmers habitually pee in pools.
