This paper says the pH will make a greater difference in solubility:TomU said:Do you think another 100 degrees will make a noticeable difference?

And, this MSDS gives the solubility of CYA as 2,000 mg/l@ 25ºC
Wikipedia puts the solubility of CYA in water at 2,700 mg/l@25ºC
Roughly converting to American units, 1 pound of CYA will dissolve in 50 gallons of water at 25ºC at saturation levels.
It would be interesting to see what the saturation numbers are for 100ºC.
