CYA in a sock

[waterbear]

I think I read a post about liquid CYA being available now...? To me, that's the easiest I recall something about it being more expensive though...

QUITE a bit more expensive in fact.
1 gallon Liquid Conditioner raises 10000 gallons about 35 ppm and costs close to $30 online.
2.75 lbs CYA raises 10000 gallons about 35 ppm, 4 lbs costs between abut $10 and $20 online.

do the math
