Hi TFP Operatives,
I recently bought a 5 litre bottle of Purox chlorinating liquid for C$5.50, with 10.8% sodium hypochlorite / 10.3% chlorine.
Bleach locally is more per litre, with only 6% sodium hypochlorite.
But Chem Geek's thread on chlorine sources states that bleach is still more cost effective per available chlorine content.
If Purox has 10.8% sodum hypochlorie vs Bleach's 6%, it seems odd that Purox has less available chlorine.
Clearly, my lack of chemistry education is letting me down here, as I'm missing something...
I thought I'd found a bargain, but maybe it's better to stick with good ol' house-hold 6%.
Do both Bleach & Chlorinating Liquid have the same 'other ingredients'?
The Purox isn't harbouring a shed-load of undesirable additives, compared to Bleach, that will mangle my water balance over time, is it?
It just seems very odd that something marketed to people with pools (i.e. with money) is cheaper than Mrs. Working-Class's bottle of Bleach.
My wife thinks it's because it's stronger therefore more difficult to use, and thus less desirable / marketable than Bleach.
Insights, as ever, make me more knowledgeable by the day.
For which I thank you in advance.
Regards - D
