I'm a tad confused [which is normal for me].
Kem-Tek 013 Dichlor is often mentioned here, yet Cyanuric Acid is also mentioned as a good stabilizer.

I noticed WalMart sells 3lbs of AquaChem Stabilizer for around $12.50, and the ingredient label lists it as 100% Cyanuric Acid. No cereal fillers, no fluff.

Is it ok to use this instead of the Kem-Tek and, if not, why not?
What's the difference?

Thanks.
