    Question about Heaters and Alkalinity

    getting a new raypak heater monday and have a question.
    My old rakpak just died after 19 Years of service !!!!
    I use TFP Recomendel levals for a SWG/ Fiberglass
    ( my pool is really gunite with fibertech surface )
    I keep the Alkalinity between 60-80
    My Raypak heater manual says Alkalninty should be 100-120
    Is this going to be a issue ???
    Will lower Alkalinity damage the tubes in the heater ?
    thanks for any advice ...

    No, lower TA will not damage the heater. There is some chance that they could use it to deny warranty coverage, but not because it has any actual effect on the heater.

    When referring to Raypak, they will try to do everything they can. "Sorry we can warranty this since we can't determine that the truck delivering it had the proper PSI of air in it's tires".
