SILAS DERENZO

is it possible to add citric acid, or acetic acid? this probably may help

Vasanthakumar Arumugam

Thanks for your information sir, I already tried with citric acid and this is powder mixing so I'm not able to use acetic acid.

Eliana Vieira Canettieri

I suggest doing the dilution little by little under agitation and heating and doing a treatment to reduce the hard water salts. You could decalcify using ion exchange resins to capture calcium and magnesium from hard water.
