Hey guys, got a quick question for you/ in need of some suggestions to my issue.
First off this is not a private personal pool, its commercial full size with a heavy bather load. An easy 200+ people per day. Outdoors during summer months, and covered in winter with a pressurized dome. Thus im seeking the help from you experienced pool guys who have possibly worked around this type scenario.
Ill post my problem first then stats.
I have been battling a constantly high pH for about a month now. No issues whatsoever this summer. Our Sanitizer, - Cal Hypo Tabs un-stablized- is fully automated. As well as our pH system which is acid only. Our sensor/computer/ and acid lines are running fine and normal thus i think its water chemistry issue.
The pH has been on average 7.8 for some time. Last night we added an additional 4 gallons(based off poolcalculator.com) of muriatic %31.45 to drop the pH to 7.45 (normal level for us). oddly enough it didnt work.
We have the beginning signs of a Mustard Algae bloom on our slope. Could this be the cause of our pH issue? Does Algae raise pH?
I know how to treat the MA, and after typing this out i suppose itll be best to treat the algae issue first, then see if there is still a pH issue. Lastly, will this high pH cause trouble for my MA treatment?
We will soon be closed for about a week to install our "bubble" over the pool for winter, so nows the best time to hit these issues. Any tips you guys have with MA or possible culprits for my high pH will help greatly.
Stats: 360,000 gal
pH- 7.8 average
Alk- 100 (slightly above our normal 80)
Temp- 82-84 F
I plan to hit the MA with roughly 100# Cal -Hypo Shock and 12# nuclo Yellow Shock and clear which has worked miracles on MA in the past.
Should i try to drop this pH before i treat the MA?
