It’s that time of year (for me anyway) to balance up the swimming pool chemicals. One of the chemicals usually added is sodium bicarbonate and the supermarket is usually the stand out place for price on that. Looked at prices online to check this year and I see Bunnings carrying a generic looking brand that rival the supermarket price.
I purchased a bag and I see it is made by HYCHLOR NSW, the same people I expect that put this on Bunnings shelf next to it.
Both are 1000g/kg sodium bicarbonate.
Similar with these two lines, though note the mass is not the same but $/Kilo for same product is noticeably different.
Looks like a gouge for the coloured packaging, as they are chemically the same one could not even argue longer life or better quality.
