NO!

Stay away from anything with an Aqua Chem or Pool Time label. These are BioLab (also owns BioGuard) brands, and have been used to pioneer some of the most predatory and worthless pool chemical voodoo soup blends.

I'm sure they sell some products that are OK, but until you are adept at reading chemical labels, those 2 brands should be a the BOTTOM of your list. I can see enough of that product picture, to tell that it's a diluted product, but not to see just what's in it. One problem with Pool Time / Aqua Chem is that they reformulate products regularly, so you cannot depend on the product name. That is, Aqua Chem 'Sum-Sooper-Chlorine-Sparkles' may have been 99% dichlor dihydrate / 55% available chlorine (good!) last year, but be a voodoo blend of dichlor + copper sulfate + borax + aluminum sulfate, with only 25% available chlorine, with pool staining copper added to the mix, this year!
