20,000 Gal pool, glass media filter, fibre glass surface, using liquid chlorine.
I had kept my TA at above 100 when I had a concrete surface. Since it was refurbished to fibre glass, the guy who did told me to not worry about TA any longer because of the fibre glass coating, which seemed odd since all the manuals insist that TA is essential to buffer the PH. I nevertheless let the TA slide to around 20 and haven't noticed any difference. Does this make sense to anyone? Appreciate any feedback and thank you.
