The CYA was 40 last time I checked it. I'm fine to raise RC if that will help. I'm curious what is more damaging to the pool if the water is full. A lower PH level or a higher FC level? As well, which would be more effective to remove the plaster stains?

I have been working on removing stains on my plaster pool walls and floor all summer. Lots of brushing and have kept the FC above normal, around 6-10ppm. The stains have softened up some but I was hoping they would be gone by the time I had to close the pool. My plans are to close the pool in...

Sounds like a plan. I'll do as you guys advise and raise the FC level up a bit and see how things progress. I guess it's just time to enjoy the water!

Looks like they stains are absolutely organic. I took a large puck and scrapped a section. It seemed to help. So, I let it sit on the floor for a bit and kept checking on it. After around 45 mins, there was a completely clean circle under it. Now, what is the best way to scrap around the floor...

You may very well be correct. I'll try the Vitamin C tablet in one area and the puck in another area. I'll report back with the results.

Sounds too easy! I'll give that a shot tonight.

Is there a procedure for the vitamin C treatment?

Ok, sounds good. I'll try the puck idea sometime in the next few days.

I am completely fine with it taking time. My concern is basically the best way to alleviate them. So if shock is around 10-12 ppm, should I plan to keep the CL around 6-8 ppm?

How high is 'elevated'? I've also read about lowering PH levels for a week or so will help to "acid wash". The water would obviously be un-swimmable but is that a suitable option? https://blog.intheswim.com/no-drain-pool-acid-wash/

Thanks for the link. I recently purchased the house and can only assume they are organic. I removed 4-5 wheel barrow full of leaves, sticks, etc from the pool when I initially opened it. So that had been sitting at the bottom of the pool for several years.

After several weeks, my pool water is finally looking good! All of the water chemical levels are excellent, per my test results and the local pool supply. Anyway, I'm now left with stains all over the plaster floor and part of the walls. What are my best options to help alleviate some of the...
