My dealer has a product from Bioguard called oxysheen. It is a non -chlorine oxidizer. The chemical name is potassium peroxy sulphate mixture. It is 43% potassium peroxymonosulphate,29%potassium bisulphate and 29% potassium sulphate .Minor ingredients are 3% potassium peroxydisulphate and 2% magnesium carbonate. Can I use this like MPS or is this something different? In Canada I can<t always find the same stuff as you Yanks. thanks ,bobhol
