Is it rough or raised? It could be scale. Is it slimy? It could be algae.
Post some test results at opening that might help diagnose the problem.

It could be considered rough but doesnt feel any worse that the normal plaster. Definetely not algae. Readings as of this afternoon:
FC - 10
CC - 0
PH - 7.0 (working on airating it up)
Cya - 30
CH - 250
TA - 120

I didn’t do testing when I first opened it but based on what I put in I’d say around 7.5-8.
2 gallons of Muratic acid and about 25 lbs of Leslie’s power powder plus over 3 days. Water was the worst it’s been since I’ve been dealing with it. Staining however was there before anything was added. It was the first thing I saw.
2 gallons of MA will lower pH by about 2.46 and TA by 40. PH well above 8.0 and TA around 160 point to scale.
Brush it a lot while the pH is low. With a stainless steel brush if you have one.

Thank you both very much. Ive read up on the zero alkalinity acid wash. Im going to do a test with my spot remover and if that is successful I’ll attempt it. This stuff is all over the pool.
Ok my Muratic acid spot remover tool took it right off. I guess I’ll be trying the zero alkalinty acid wash. The only question I have on that is what does FC need to be while doing it? I didn’t see anything on that. Thanks again!
