Test results on new pool in Tucson

Regardless, it's not the pollen that is causing your chlorine demand.

Actually, pollen in the water will increase chlorine consumption. Anything organic in the water will. It is not the entire cause of his issue but just wanted to clarify that anything organic in the water (pollen, leaves, etc.) will use more chlorine.

Retested this am, spa ph at 7.2, chlorine levels held at 17 at both pool and spa. I think I'm making progress ( but won't let foot off gas yet)

Important clarification, thanks!

I'm not sure if this helps or not, but, mary jo had a very similar situation in this thread: http://www.poolforum.com/pf2/showthread.php/25802-Clear-but-no-chlorine. The pool had high CYA and chlorine demand after an extended period of insufficient chlorination. The good news is that it was eventually resolved by maintaining shock level FC for a very long time.

Mary Jo (see above link) read your thread and wondered about your CC. Last reading I saw was on the 14th or so. Spa? Pool? Either greater than 0.5?

Cc is still 0. Cl this am was 17., and I added a gallon between the spa and pool, retested at 5 pm, cl was 20 in both. I think I have this thing on the run, just not sur what it was.

We may never know what it was; sometimes it just doesn't matter if it's fixed. Who knows what you inherited with your pool.

My friend's inherited pool (which I mentioned before), had thick gobs of algae in the insides of their jets. Still fighting demand there cause I think there has to be algae in the feeder lines which we can't manually clean. Not sure what we're gonna do about that...

Keeping your bleach additions >=25 will only help.

I did ask for input on your pool/spa connection, but no responses yet. Still seems strange to me that you could accidentally drain the spa but I already admitted my ignorance of spa issues. It hope that the spa will hold the key for you and that stability is around the corner!

Maybe it was when I put the vacuum in there?
