Having joined TFP this past spring, I have had a sparkly clean and trouble free pool all summer and have thoroughly enjoyed the process of regular testing and listening to all the ooos and aahhs of a clean, good looking pool.
CH 425 (fill 75)
TA 60 (fill 275)
How concerned should I be when bringing PH from 7.8 to 7.2 and TA from 80 to 60 adding MA according to Pool Math and CSI reads -0.66 and corrosion likely?
In the summer I add MA every week to 10 days and usually it is in the above range in order to keep my TA down. I was hoping for a leveling off on PH by now, but that may not happen with SWG, falls and plaster. I was surprised to see my fill water TA is 275, but have read since many others have higher.
Since this CSI level only lasts for a few days till levels start drifting up, I'm wondering if it's a big deal.
I know it spent a lot of time at the other end before TFP, since there was lots of scaling back then and much more frequent cell cleaning.
