Also, digital photometers are not immune to the blunders of the people using them. Improper handling or infrequent replacement of the water-sample vials can cause false readings, as reagents or elements of the pool water itself can cause staining. And with the handling of reagents of any form can come a variety of other complications. In DiSalvatore's case, the alkalinity test on her digital units requires a full minute's worth of commingling of the water sample and the reagent. It sounds simple, she says, but as many pool operators can attest, many part-time pool employees have a knack for overlooking seemingly mundane testing details. "We have part-time lifeguards who have little or no certifications or qualifications as far as operating an aquatics facility or a pool, and they are able to use the system pretty easily overall, without much error," says DiSalvatore. "That is, as long as they are able to wait that full minute for that one reagent."Despite this advantage, test strips are not known for their accuracy, says Antoniou. Leaving a strip in too much or too little contact with water can skew results, and the ranges representing measurements on strips' color comparators tend to be on the broad side.*"I don't know of any health department that has approved the use of test strips as a sole means for the operator to check water chemistry," says Antoniou.*

Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
