HTH Tablets with NO CYA

[mswlogo]

I know in the past no such thing existed.

But I noticed HTH now sells duration tablets that say right in big letters.

"Will not over condition" and "No CYA".

Is this the same as using powered "Super Socket" in tabket form?

HTH stills sells the Pace brand tablets which do contain CYA.

Are there other brands now with no CYA?

My pool was definitely headed for over conditioning and I've been using liquid and powered this year so far to allow CYA to come down a bit.

The Duration tablets are cal-hypo. If you can deal with the calcium addition to the ppol, they are fine. They cannot be used in the same chlorine feeder used for trichlor or dichlor due to explosion risk and the physical nature of the tablets.

The new version of the DURATION tabs are junk. They are 48% cal-hypo and they don't last days without dissolving, they barely last hours. The older ones were wrapped in a plastic capsule that worked far better. HTH's sister company, PoolLife (another Arch Chem company) still sells them as PoolLife Active Cleaning Caplets. But their website doesn't say the active percent of Chlorine...typical of Arch.

Sustain makes a Cal-Hypo puck that lasts five to seven days for me, I run my system 12 hours per day in 6 hour increments. I use them when I am away on business and can't add bleach. They make other items as well but I only use these pucks. www.askjoepool.com for a dealer, just type in your zip code.

When I checked our your link Sustain did NOT list the ingredients in their chlorinators, just lots of useless adjectives. They didn't say "Cal-Hypo" or "Tri-chlor".

As soon as chemical companies get vague about what they are putting in their chemicals, they ain't going in MY water! My kids get that water in their mouths, they swallow some and NOTHING gets added by me that I don't know EXACTLY what's in it. Ever. EVER!

Just trying to help someone out. The bucket says "68% Calcium Hypochlorite, 32% Inert Ingredients." Also states "Minimum 65% Available Chlorine." and "colored blue for safety." As I said, I don't use any of their other products, just these tabs when I'm not able to add bleach.
