No. Not at all. This is the stuff we call Di-Chlor. DO NOT MIX IT WITH CAL-HYPO! VERY, VERY DANGEROUS!
There are many threads here on the side effects of ALL the various chlorinators.
I normally use one pound of shock (calcium hypochlorite) in the one pound bags for convenience (15,000 gal pool).
I was at target and they were clearing out the formentioned chemical for 1.25/pound. The label states, 56% available chlorine.
Anyway, is the stuff acceptable to use in a normal chlorinated in-ground pool (GUNITE) ? Any side effects in using this stuff vs bleach vs regular shock (cal. hypo.) ???
Thanks,

Di-Chlor tends to lower pH and adds Cyanuric Acid, also called CYA or Stabilizer. While you need CYA (except in indoor pools, too much is a problem.
Cal-Hypo tends to raise pH and adds calcium. You need calcium for gunite pools and for any pool with stone and morter/plaster work, but not for vinyl. Too much is a problem. It is also the most volatile. Be careful with it.
Tri-Chlor is the typical tablets. Like Di-Chlor, it lowers pH and add CYA, but a lot more than Di-chlor.
Regular bleach or liquid chlorine has essentially NO side effects. While its pH is high, the chlorine reactions in the water offset that virtually perfectly. It adds a little bit of salt, but it's not like adding several hundred pounds.
Hope this helps.
