Well it had to happen up here eventually.
Walmart is now selling HTH/Arch cal hypo at 47% in a 11.4 kilogram
pail, down from 65% last year, and roughly the same price ($56.93 CDN)
as last year's 65%. A 38.3% drop.
The 65% is now called "Super Sock It", again from HTH/Arch, and that's
only available in a 2.27 kilogram pail at $16.93.
The price for a 1 ppm increase in 10k liters for the crap stuff is
$0.1062 compared to $0.1146 for the 65% grade. Hummmph.
Lucky for me I still can get 70% elsewhere.
My unnamed source over at Arch told me they purposely downgraded the
chlorine content following requests from Walmart and others. Too much
of a fire hazard.
Next to come our Canadian Tire hardware stores will no longer be
carrying rope, because there's too much of a suicide risk.
HTH used to be good, now they're going the Biogard way.
