Test results on new pool in Tucson

[BigDave]

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?

Not a hydraulics person but would that explain refill??? The responses I requested were from spa people, not you, btw. Was looking for their expert input, not as a criticism of you!

BTW, like your pic on your profile! Make that your avatar or better yet a pic of the pool and spa. Signature too? Here's mine for guidance: 26K gal 20x40 rectangular IG vinyl pool; Apr 2014: New pump, liner, auto-cover, & water; Pentair Whisperflo 1HP pump on 24/7; Pentair Trition sand filter; Cover/Star CS-500 auto cover; Taylor K-2006, OTO
