I noticed something today that I would like to get clarification on. On the Recommended Levels document, on this site, a plaster pool shows Alkalinity should be 70-90+. I have been shooting for 80. However, I just noticed in my TF-100 kit it recommends 100-120.
I know Alkalinity and Ph are related and I have been having trouble for the last 10 days keeping my Ph down. I will get it down to 7.5 and it will start creeping back up until I have to adjust it back down.
Which should I follow and could the problem with my creeping Ph be that I am keeping my TA too low?
Last night pH was at 8.0 so I added pH Minus (I am not comfortable with using Muriatic Acid). It is at 7.6 this morning and TA is at 60.
