I inherited a 20 kilo (44 pound) industrial chlorine powder container brand new that came from previous owners professional pool service company. Is it safe to assume its cal-hypo? Its extremely strong and powerful (fumes etc). Is it also safe to assume it is probably in the 65% range when doing my chemical math when adding it to the pool?
They also left behind a container of pool acidet (I assume for lowering Ph) and also a large jug of what I assume to be clarifer.
