    Should I increase TA?

    My water has been extremely stable for the past 2 months with this morning's test being the norm. I am losing 1 FC consistently per day & the PH creeps up about .2 weekly. I am currently targeting a PH of 7.2 - 7.6.
    I have a little bit of staining / tough buildup in some areas & I am keeping PH on the low side of normal to help combat this along with brushing.

    My question is, should I raise the Total Alkalinity or am I OK with it hanging out at 60?

    60 is fine. I keep mine between 50 & 60. If I don't pH rises much too fast for my liking.

    Rather than raise TA, why not let the pH hang out at the higher end? Say, 7.6>7.8. Your CSI is pretty low if you knock the pH down to 7.2.

    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!

    I am holding th PH down for a few weeks while trying to brush off some brown streaks. Inherited a pool with a lot of gritty buildup & I am knocking down the last few streaks. Seems I read here that a lower PH can help with that. The pool likes to hang at a PH of 7.5-7.6
