Added a few more pics of the entire pool to my earlier photo post

No water softener unfortunately!

I appreciate you looking at that but I wasn’t updating Poolmath after my initial entry nine months ago. I’ve been keeping a manual log and when I checked those numbers in Poolmath all indicated I would have had a negative CSI as I’ve been keeping pH low. This scaling occurred during a three...

It’s good to know TFPC does not endorse acid washing to remove scale, most things make it sound like acid washing is as commonplace as cleaning your filter basket! I think I’ve decided that I’m going to simply change the water and continue maintaining a negative CSI. I did attempt to maintain a...

Added a few pics as I’m in the process of draining. Not surprisingly, the citric acid didn’t have an effect. The 10-year old plaster appears to be in very good shape. The discoloration seems to be primarily scale. Should I attempt an acid wash to see if it has any effect on the scale? Consult a...

I do not know any specifics regarding the plaster that was installed 10 years ago but it’s definitely standard white plaster. There are a few small quarter sized spots on the side where the plaster is degrading (not really chipping). Primarily it’s just stained. I have some citric acid left over...

Hi all, I have a pool at my home where I’ve been told the plaster was redone approximately 10 years ago. It needs a water change and it has some staining so I was researching my options and also discussing with a local pool servicer. This person said that I should not do an acid wash because it...

I really appreciate all the input. I actually reduced pH to 7.2 last night because I recently learned that lower pH improves the effectiveness of chlorine. I’ll be diligent about keeping the pH low for the next couple of weeks and report back. As of today, things are the same. Water looks good...

I assumed it was typical to lose a fairly decent amount of FC per day during Phoenix summers... but I did not expect 3 ppm per day. That’s a lot of daily chlorination! I’ve been using 1 gallon of 10% chlorinating liquid every two days, administered after the sun goes down. By the end of day two...
