Bunning's $32 Vs Pool Shop's $125 Chlorine

anonymoususer on 10/07/2014 - 08:52

I noticed considerable difference in cost for same quality and same quantity Chlorine
when checked with local pool shop (swimmart) and Bunnings.

Not sure why its so much difference? Wondering if there is any problem in buying this 10kg-granular-pool-chlorine from Bunnings to save $$$.

Appreciate your inputs guys.

The bunnings stuff is Calcium Hypochlorite.

Cant really see the front label of the pool shop stuff, but it looks like Sodium Dichloro-something.

The difference is that The Pool shops sodium stuff is stabilized chlorine (it contains acid), where as the bunnings stuff is un-stabilized.

Bunnings stuff dissipates faster, used as shock treatment (chuck it in, chlorinates fast and for a shorter period)

Pool shop stuff has a higher acidity and stays in the water longer, but is not as powerful of an oxidizer (doesn't dissipate as fast), so not good for shock treatment.

Calcium in the bunnings stuff can build up and harden the water

Acid in the pool shop stuff can build up and block chlorine release in the water

Best to google "hypochlor vs dichlor pool"

  Thanks :)
  
  Just a basic Q - what is shock treatment ?

    Using a large amount of chemical to apply a large, fast change to water, with the idea that the chemical will be used up/absorbed in a short period. You then test & add chemicals to get the water to a usable/finished state.
    
    Kind of like nuking the water and starting from scratch, rather than slowly tweaking away for a long time.
