I have an Intex that gets drained and stored every year. If I went the cheap route with borax and acid, would borates still be worth it? And would I really have to lower my TA to 80 if it's just going to get drained at the end of the season anyway? My fill water has a TA around 180. I tried lowering my TA last year, but found it not worth the effort. So if I wanted to borate my pool, would lowering the TA be an absolute must?
