Bromine Chemistry Question

[PoolDoc]

You've got a broken anti-virus program -- which one is it?

Anyhow: http://www.poolforum.com/pf2/showthread.php/18597

1.) It is called Trend Micro Worry-Free Business Security Services. Our school just purchased the service this year. (I'm at work).

2.) In A2 above, I add 1/2 bag doses of calcium hypochlorite.... How frequently do I add a dose? How do I know when to stop?

3.)Thanks for the new link. Do you think the process in A2 above will be enough to clear out any metals or should I do a bucket test for metals before I start adding borates? Also, why do you test fill water?

Thanks again.

Arg-h. No wonder.

My wife, who is a elementary resource teacher (she teaches the ones who are about to fail the standardized test!), can barely access the internet from school. They have the most awkward, cumbersome system I've ever seen. It just got worse, since some kids were able to bring up porn on a number of monitors, recently.

I'm NOT going to worry about the fact that pool9.net is blocked on some school site. Typically those blocks are set to block everything by default and then allow by selection.

The link works from home just fine.

Anyway, may I send you a picture tomorrow? I now have a question about what looks like iron stains on my stairs. They appeared after a huge rain last night. I still had my pool uncovered through most of the deluge. The water is also looking dull. It also looks slightly tinted but that's when I'm looking towards the stairs and that could be a reflection...?

After waiting 3 days (after a TA reading < 150 ppm), retest both pH and TA, and report results here. Do NOT test either pH or TA during the 3 days you wait.

Okee-Doke! Test results tonight:
FC: 2.0
pH: 7.5
TA: 100-110 (did get a little more red with last drop but pretty red at 100)
CH: 60-70
CYA: almost there but I will retest in daylight

What do I do next?!?!

Thanks for the new handle!

Since I know you guys are busy, please just let me know if I am off base on my next step.

I am thinking that now that my TA is good, I should start using the calcium hypolchorite per instructions to try to reduce metals in the water. My water is dull looking and there is definitely an orange tinge on my stairs.

If you ALREADY have staining, you may want to lift the stains, before using the cal hypo.

However, you can certainly use the cal hypo now, and then again, later.

That might even be best, since it seems to take more than one pass, to lift the stains and then get all the metals out of the water.

Okay. Heading out now to test pH and add borax. The stains are very light. I think by "lifting stains" you mean sequestrate the metals, so I will buy some HEDP tomorrow. If I am wrong on this, just let me know. Otherwise, no need to respond.
