Chlorine will not hold

[wposton84]

Thanks for the assistance, Carl. I greatly appreciate it.

This is exactly the same response I found on another forum, so it sounds like reducing the CYA is the only way to go.

Just to be clear, the only way to do this is to drain 50%of the pool, correct?

Thanks

Will

Not Carl, but ... yes. Unfortunately, that is the only way to reduce the cya. Even if you do that, your cya will still be 50 which is OK, but you really don't want it any higher than that. As Carl said, at that level, you won't be able to use any more trichlor pucks in this pool or the cya will soon be right back up to 100 again.

I assume, from your post, that you are in the pool industry -- servicing pools? Forum rules are that anyone in any aspect of the pool industry must identify themselves as such in each and every post. By the way, welcome to the forum!

You should be able to put that information, that you are in the pool industry, in your signature line so you don't have to think about it each time.

It doesn't matter if Lisa (WaterMom,), Jan (aylad), Al (Poconos) or Ben (PoolDoc) answers instead of me. The message will be the same.

There are others whose advice will be the same or similar, but we make up the administration of the PoolForum, with Ben as the owner, and we 4 as the moderators.

I'm not sure I would consider myself "in the industry", but I do care for two pools: my own and a friend's. I will gladly identify myself if those are the rules.

I assume this can be included in my signature, what should I say, exactly?

[Watermom]

If that is all you do besides your own pool is care for one friend's pool, then don't worry about it. I thought that might be your job. Never mind, and again, glad to have you as part of our forum. Hope you will find a lot of good information here that can help you!

Thank you so much for the advise and the welcoming attitude.

It's nice to know there are some knowledgeable people not trying to sell me a myriad of chemicals.

Do you recommend a specific test kit for checking chemicals? There is one model that seems to keep popping up in my searches and I was wondering if it was your kit of choice as well.

[CarlD]

Yeah, A really good one is the Taylor K-2006 or K-2006C, both from Taylortechnologies.com

Equivalent is the FAS-DPD Service Test Kit from Leslies on-line service.

Search out Chem_geek's recent post--he had a link to the Taylor at a great price. Expect to pay $50-$80 for the kit and it will pay you back 100x over! I have something like 3 versions of it in various forms.

At www.amantoind.com you can get the Taylor K2006 for $46.25, product #13633.

The 2006 is the basic kit with .75 oz size reagent bottles. The 2006C is the same kit with 2 oz size bottles. This supplier also sells Taylor refills in a variety of sizes at good prices. I've found it very cost effective to buy the basic 2006 and stock up with larger sizes of DPD powder, titrating reagent, and CYA testing solution, all of which I keep in the beer and wine refrigerator (not to be confused with the Yuengling Lager! )
