OK, so TFP says my TA should be 70-90+ since I'm using liquid chlorine. And the Borate Sticky says to adjust TA first. I'm currently at TA 110, which doesn't seem unreasonable, though I don't really know how much "+" is OK on that 70-90+ range. Is there any utility in lowering my TA to say, 80, before I start adding borates (I'll be using MA and Borax)? I do have a bit of pH creep, as my pH went from 7.4 to 7.8 over the past few weeks. Of course, adding MA will lower pH (and TA), but it's supposed to be essentially no change since I'm adding all the Borax as well.
CYA 20 (goal 30, getting there)
pH 7.8 (goal 7.5, just adjusted a few min ago)
23000 gal IG, plaster, no regular aeration (though I could point a return to the surface), DE filter.
So, my main question is: Do I need to lower TA to 70-90 before starting the process?
