    start up 1 wk's my numbers....

    pH = 7.4
    alkalinity = 70
    cya = 0
    total hardness = 70
    total chlorine = 0
    free chlorine = 0

    28,000 gallon gunite/plaster pool w/ 60sq ft DE filter

    pool store recommended adding

    4 lbs alkalinity increaser
    3 lbs of shock
    20 lbs of calcium hardness increaser

    I added 6 7oz chlorine pucks to the chlorinator on Sat night and set it all the way up...still not registering any chlorine levels. Are the above recommendations appropriate for a brand new plaster pool? How critical is the calcium harness increaser right now? our harness reading was 0 on Sunday, now it's 70.

    A new plaster pool will normally bring the alkalinity and calcium levels up all by it's self as the plaster cures. If you add any now it will end up being too high in a few weeks.

    CYA can test as zero when it is as high as 15 (or perhaps 20). I would just keep on using the trichlor pucks for a while till you have a good CYA level.
