I opened my pool this year to find this yellowish/brownish stuff all over the pool. I tried a chlorine puck and vitamin c. Neither seemed to work. Is it calcium or metal maybe? Any help would be appreciated!
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
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.
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!
