Our church pool chemistry is usually maintained by the lifeguards but they're told to call us oldtimers if they see a problem.  Lifeguard just called to say that he's been adding soda ash daily to keep pH up above 7.4 but that alkalinity has dropped to almost nothing.  Advice??

Hi Hal:) 
Without full test numbers all I can say is lots of baking soda! We can't be more specific without test #s and aprox. gallonage,
I doubt it is a major problem, you just need to 'tweek' the chem levels:cool:

Thanks, Ted.  It's great to be back in the Forum.  The biggest challenge today is where to source the baking soda.  I doubt we'll be able to do anything today but the kids tell me there's not too much traffic on Saturday evening.  I'm working on other sources for 50# bags but probably won't have it before Monday.  Pool's closed on Sunday, even when it's 98 outside.  Pool's about 175K gallons, CYA's about 95, CL at least 8, pH 7.4( I got these over the phone from the lifeguard.)  Bioguard 1200 test kit.  He said the alk test sample goes from green to clear after 3 or 4 drops.  He's added 50# soda ash in 1 week.  Last time I tested the CH it was 200-250.  Thanks for your help.
