If this was your fill water, what would you do?

[BigDave]

Congrats, sounds like your fill and startup went well.

TA shouldn't move a whole lot but what's "normal" will be uniquely "normal" for your pool. Keep an eye on TA and pH stability for a while to get a feel for what's normal for your pool. A TA about 80 may be ideal for bleach chlorinated pools but if pH stays stable, 100 should be just fine.

Here is graphical data of my weeks activity.

Nice recordkeeping! What kind of chlorine are you adding? How did you add the CYA?

[Bosch232]

Chlorine and CYA are just HTH from Wal Mart. Granular versions of both.

I'm a bit uncertain about the CYA, because I added 2 lbs and the test still says ZERO.
So I'm not quite sure I've got that dialed in.

[Bosch232]

I didn't exactly answer your question.. I've added both to the skimmer, slowly pouring it in.

[BigDave]

CYA can take a long time to dissolve - don't bother testing for 4-5 days after adding granular CYA.

There are a couple types of powder chlorine - most likely Dichlor or Cal-hypo. Dichlor adds CYA, Cal-hypo doesn't. Either is OK right now as you need CYA but it's good to know what to expect. Which do you have?

[Bosch232]

Thanks for the heads-up about CYA - I would have probably added more too soon if you hadn't told me that.
I put in 47% cal-hypo. This: http://www.walmart.com/ip/HTH-Chlori...nules/17043619

So far, the water is sparkling clear.
Thank you for your help in my start up.

It's only 45 deg here, what crap...
