HTH Non-stabilized chlorine tablets

[CarlD]

Those are called Cal-Hypo Duration tablets. I have them too. But I don't use them--they are supposed to last 5-7 days in the skimmer, but the new ones dissolve in less than 12 hours. They don't add stabilizer, but they do add calcium.

I do not recommend them because they do not perform as advertised even if you EXACTLY follow the directions.

Ah yes, Duration - that's it. I had the same experience with them dissolving quickly.

Thanks.

I was in WalMart recently and came across the Duration tabs. Just as Carl said, they were only 46% (or 48) chlorine not the 68% so I didn't bother with them. This weekend I stopped in a pool store that carries HTH products and their Duration tabs were 68% with the plastic case around them. I also found an on-line vendor that sells the Poolife version (same parent company - Arch chemicals) that also looks like the 68% version (I googled Poolife Active Cleaning Capsules).

I wonder if the 46% versions are a "special version" of the product that sell for less $$. I've heard about this happening with the big box stores - they want a lower price and the manufacturer meets that price by cutting corners. I didn't notice what WalMart was selling theirs for so I can't compare but a 6 capsule pack at the pool store was 10.99 and they had a bigger bucket (25 lb?) for 59.99.

Anyway, I picked up a few to use mainly when I go away - I figure I can put one in the skimmer before I leave and ask a neighbor to put another one in later in the week.

I cannot answer your questions too accurately, but I know that Arch claimed something about WalMart demanding the lower chlorine level. I personally think that's BS.

Arch has been, in my opinion, "ruining" the HTH line for the last couple of years. Unless I could find the 68% tablets or the 5-way drop test kit, I will no longer buy HTH stuff.

Vanhout,

I remember reading on this forum last year that HTH had discontinued this product. However, last year I was able to buy it online. This year, the 68% type is also on clearance at www.poolsupplies.com $49.99 for 23.5 pounds. I've decided to skip it this year and rely 100% on the bleach. We'll see how that goes.

By the way, it's called HTH Duration Capsules.
