A friend who just sold his house with a pool gave me a bunch of something call Shock Plus 4 in 1 pool shock. The only active ingredient is Sodium Dichloro-S-Triazinetrione. Is that just a mixture of chlorine and stabilizer? If so I will use for chlorine and just keep careful track of my stabilizer level? Or is there something else in it that I don't want in pool. I know this forum recommends bleach only, but bleach is expensive and I would like to use this gift if it is safe.
What is Sodium Dichloro-S-Triazinetrione ?

It is Dichlor.
A stabilized, granular, fast-dissolving form of chlorine. Because it dissolves so easily, it is often sold as “shock”. Like trichlor, dichlor adds chlorine and CYA to your water and lowers the pH. Use of dichlor can raise your CYA level very quickly.

Careful with the 4 in 1 products...they often contain copper or other troublesome metals.

Typically the shock labeled 4n1 does not have copper in them. It would show on the ingredient list.

If it’s the Clorox branded 4 in 1 it has borax to counteract the acidity of the dichlor and aluminum sulfate to act as a clarifier.
it can turn hair green and stain pool surfaces, and is hard to get rid except by replacing the water.
