Anyone knows how public swimming pools are maintained? Do they completely change the pool water at the end of day, or weekly? Anything they do to the pool overnight (just circulate like daytime, or do nothing, or change entire pool water)? Is the water cleaner in early morning than evening because of this? Thanks.
I think what mikedivl meant to say was Salt Cell System - not salt filtration system.
hofffam - you are correct there are an assortment of Sand, DE, and Cartridge filtration systems.
A Salt Cell System takes salt water (NaCl), passes it over electrically charged plates (in a process called electrolysis) to release the chlorine in the salt. NaCl in and HOCl out. Although chlorine is not used per se, chlorine is still present.
Yes, pools with Salt Cell Systems have water that is much "softer" and "easier" on the skin. Over time, Salt Cell Systems save money too.
The pH is the key to skin irritation -- too high or too low and you will have issues. The pH of your eyes is approx 7.4 - 7.6 (a greater population on the higher side). That is why the swimming pool guidelines have been established as such. For the ease and comfort of your body (& parts).
Regarding the water temp -- the activities taking place in the pool will dictate the temperature more than the local ordinance in most jurisdictions.
