One question that we seem to get quite often from prospective pool users is whether the Zeta Rod will help them with their pool. Primary concern seems to be with the "bath tub ring" that forms around the water level and the use of chlorine.
Mike Pitts, President of Zeta Corporation explains:
"The continuous evaporation of water (typically in Arizona 1" / day) quickly raises the concentration of mineral matter to the saturation point and precipitation of all mineral salts is very active. Pool filters handle much of the precipitate load, pool vacuuming and pool cleaning services get the rest. Evaporation of the wet splash zone establishes the "bathtub ring". A year long demo in Phoenix proved complete "ring " prevention and slow removal or softening of the old hard deposit.
Public pool chlorine is a legal mandate for active CL residual, home pools don't fall under this mandate, so they are generally fed chlorine by appearance and by demand as needed for algae control.
Liquid chlorine commonly used in large facilities yields acid condition requiring neutralization with soda ash. Smaller pools and some large use calcium hypochlorite with obvious addition of both high alkali and calcium. Sodium hypo' is generally considered too expensive for pool use.
Numerous home ZR residential pool owners report improved pool conditions even with just the continuous refill of evaporation by Zeta treated city water. some residential use is coming on of the ZR and more is expected and justified quickly because of the high cost of the service when cleaning is contracted to a pool service. 3k - 4k + per year
Bacteria is not a prime concern ion home pools because of over us of chlorine public pools have continuous testing program to assure hygiene
The deal with ZR in pools is the expensive ring cleaning payout with much more clear water in the pool . Water features of home pools -rock, water falls etc quickly lime up with unsightly white deposits-- ZR minimizes this."
