Mark,

Thanks for replying... We run the filter pump from about 9:00am to 5:00pm, but about half of it is run at low speed. Also, salt level is reading 3100ppm. Is it safe to boost the chlorinator output higher than the current level of 50% for the pool and 10% for the spa?

My combined chlorine is also negligible. PH level is at about 7.8, alkalinity about 110ppm, and calcium hardness is about 230ppm. I'm using the best test kit Leslie's has, but keep hearing how people 'order' theirs through the mail. Is this adequate?

We were in the spa last night, and my wife thought she smelled a 'funny' odor in the water. I was really wondering if this is due to the low chlorine level. Do I need to break down and throw some bleach in there, or maybe shock it using the chlorinator?

Hey, thanks for your help...

Mike
