Low Chlorine Problems

[nscclukas]

That makes sense, it's hard to calculate how much Cl to add when you don't know the strength. I found a great website today, all you will probably want to know about Cl & then some:
[ DELETED BY ADMIN -- SEE EXPLANATION BELOW ]

They explain that Liquid Cl "LC" from the manufacturer is 15%, but in two weeks it's strength is 12.5%, & in 30 days down to 9% strength. So if it was from the spring it's probably no stronger than the recently stocked Walmart 6% bleach. The good news from dumping all this liquid Cl in my pool is it has effectively lowered my CYA. It is now reading 78 I'm guessing because of the high Cl demand from the algae, the CYA is bonding with all the liquid Cl I have been adding, which is being consumed by the algae? Still not cleared up, but making slow progress.

Another interesting point made in the article:

Sorry, Nscc;

The point about the deterioration of high strength bleach, when stored at high temps, is generally valid even if the numbers aren't as simple as they make it. It's a point I often make myself.

But, the rest of the article is a mis-mash of half-truths and out-right errors, some of which are deliberate, at least on the part of the original writers.

If you want to repost in the "China Shop" and debate the details there, you may. But I don't allow that sort of bogus information in the general sections.

I wrote a longer post, but then realized that you probably posted this innocently, and had no idea how bogus the material on that page was.

Good luck with your pool!

OK Thanks...I will continue reading & learning. The chemistry involved in all of this gets way over my head. I really appreciate you being willing to share your wealth of knowledge with all of us. I'm surprised you don't get fed up with having to answer the same questions day after day, year after year. Thanks

Well, one of the great benefits of working with people this way, is that they can't see when I'm rolling my eyes.

Good answer, Ben. That made me laugh!
