Any differences in dichlor?

[Max78]

Is there any difference in the 2 types of diclor below?

Sodium Dichloro-s-Triazinetrione Hydrated
Sodium Dichloro-s-Triazinetrione Dihydrate

Both are 99% with 1% inert ingredients
The first is 56% available chlorine
The second is 55% available chlorine.

The only difference I see is in the last word (Hydrated vs. Dihydrate).  The type that came with my start up kit was the "Dihydrate".  I purchased a difference kind and noticed it said "Hydrated".  Just wondering.  Thanks!

I guess I'll step up first and say:

Max;

I would not worry about the difference. You would need a microscope to see it.

Fritz;

There are five form of chlorine approved for use is pools:
Sodium Hypochloride (liquid)
Calcium Hypochloride (granular)
Tri-Chlor (tablet or granular-stabilized)
Dichlor (granular only - stabilized)
Lithchlor (granular)

Dichlor is OK by all manufacturers.
Before using trichlor or lithchlor, consult the manufacturer paperwork. Don't even think about using the other two in tub.

Thanks for the replies.  I figured if I didn't ask that the one I was using would be something that I wasn't supposed to.  The one I just bought (the "hydrated") is by HTH and says Chlorinating Granules for Spas.  The kind I had previously (the "dihydrate") was by Rendezvous.

To confuse matters more, dichlor also comes in different strengths, I've seen 52%, 55%, 56% and 62%. the higher the strength the less chlorine is used to get to the PPM you want.

Of course you have to measure the $$ difference to the amount used - which one be more economical in the long run or will they equal out.

Fritz - As far as I know only Emerald Spas says it's OK to use trichlor in their tubs. They have a feeder system in their filters to feed either bromine or trichlor.
