Hey all. Haven’t been on here in a while. I have some major concerns with my pool. The plaster has got worse over the last year. With what I assume is calcium build up. Yet it is always on range. I don’t know what to do at this point. Pool is only 4 years old. Thoughts?

You do not record your pool water chemistry test results in your Poolmath. Can you post a full set? How do you chlorinate? Any use of metal based algaecides?
Yes I can do that. I use liquid chlorine and Muriatic acid to balance PH. I was on top of chemicals since day 1. I don’t use any algaecides. Just weekly perfect once in a while. I am poor at using chlorine tablets though

I don’t. That’s the problem.
I had a profile that showed my pool. 24000 gallons. In ground. Plaster.
PH was at 8.0 I added half gallons of muriatic.
Chlorine at 1. Have 4 gallons to put in.
TA =90
CH=350
I can’t check the CYA. I’m out of the R-0013

No.
I am not convinced it is calcium scale. Can you get any of it off the plaster and test it with acid?
You can do an acid wash. But that will impact the plaster negatively.

What do you mean by this?
Can you post a full set of test results?
This looks more like mottling than calcium scale to me.
