Finally got some K2006C numbers.. please look

Pool water looks much better this morning.

pH - 7.6 FC - 12

Is the pH really 7.6 with that chlorine level? The pool calculator says I should have added 3lbs 6oz to go from 7.2 to 7.6 so seeing that jump in pH using only 2.5lbs and reading about false ph level readings possible with high chlorine makes me wonder.

Thanks all! Almost there.. stopping at a pool store today to see if they have what I need conditioner wise without breaking the bank.

With a K-2006, you can typically expect to get a pretty accurate pH reading with chlorine levels up to about 15pm. Pool calculators are not exact especially since volume of a pool is an estimate really.

You may be able to find CYA at Walmart. If not, get it at the pool store but don't let them convince you that you need a bunch of other stuff!

Glad to hear my pH might finally be correct. See how long it lasts.

This is the stabilizer my local pool store sells.. [ http://www.namcopool.com/pool/pool-chemicals/water-balancers/5-lbs-conditioner.html ] Is this stuff good as far as its chemical composition? Cant zoom in enough to read the label. It works out to be the same price per pound as the Kem-Tek PoolDoc recommended earlier.

Also, something is buggy with this forum.. believe it or not, I think sometimes when I hit the post quick reply button.. instead of getting the "wait for a moderator to review" message.. I get nothing.

I looked at the link but I also can't read the label to know for sure that it is only CYA and nothing else. It is probably fine, but I think I'd buy from someone else where I could be sure that there is nothing in there except cyanuric or isocyanuric acid.

[PoolDoc]

It's not throwing errors that I'm forced to check, right now . . . so I'm not gonna. We're absolutely swamped with new users, plus I've got some major software upgrades in the works, so if it's not breaking something serious, I'm not getting out the digital backhoe, and hunting for it.

But, if you want to see if something breaks, try this: http://www.poolforum.com/pf2/showthr...6278-Pool-Info Once I have it fully tested, completing it will be required of all active posters. By the way, you will NOT be able to post in that section.

With respect to the Namco product, I followed the link and have no quick way to tell. I'm not going to dig right now, to see if it's the same. Where we (the PoolForum and I) are probably going is to ID a few sources of decent product that may be available locally PLUS links to Amazon product we know (or as close as I can get) is OK. There are just too many blends, labels, re-labels and name games for me to try to look at every stinking product and even annual revisions. Even when I have SwimmingPoolResearch fully operational, the MSDS and product sheets there will be the most recent available to us . . . but that does NOT guarantee that a company has not pulled a switcheroo on products, like cyanuric acid, that are not EPA regulated.

Bottom line: you're own your own with the Namco stuff. I haven't seen blended (diluted!) granular cyanuric acid yet, but I'm bet it's out there!

[mastamoon]

Yeah there is at least 2 missing posts from me. One if which describes what the cya I got contains. Label says cya and sodium bicarbonate but has no percentages. Is that OK?

Other part of that post was about shock at the pool store. 12.5% sodium hypochlorite gallons for 2.99. Which is the dame price I get 6% bleach for. Any reason to just not buy the liquid shock? Is it goop? Doesn't list any other active ingredients.

[Watermom]

I would just look for CYA that has cyanuric acid (or isocyanuric acid) only. What you bought also has baking soda in it which will also raise your alk. Your alk is a little low and could stand to come up some but I have no way to know how much. The pool shock that is 12.5% sodium hypochlorite is fine. That is the same thing as bleach but just at at a higher concentration, and that would be a good price for it.

[mastamoon]

I fat fingered that price if shock.. its actually 5.99. So in reality I would be getting .5% free over my 3 dollar gallons of bleach.

My alk was a bit low so ill add 2 lbs and see what happens. Stupid pool store has a no chemicals return policy.

If you mean, will it hurt your pool? Probably not. If you mean, should you buy it in the future? No, that's how pool companies play games to sell less for more. Is this the Namco product?

It may be a good deal. There are two problems. First, if it's not fresh, and not kept cool, it breaks down VERY rapidly at summer time temperatures, releasing oxygen gas. Second, household bleach is usually filtered for iron, but not all industrial bleach is. You can test both: add household bleach one evening, and see how much FC increases after 1 hour. Repeat with the industrial bleach. If it increases 2x as much (or is close) it's a good deal. Then, take the used household bleach, and put about a quart of industrial bleach in it. (Watch the spills: the 15% bleach I used to work with makes cotton 'evaporate'!!) Put the jug in the hottest place you can find around the hose, preferably also exposed to sunlight. Leave the lid a little loose. Check it after two weeks or so. If there's a bunch of iron sediment in the bottom, you may want to think twice.
