I went into Woolworths and was looking at chlorine for my pool.. it had gone a bit green and it was time to give it a shock and some algicide.... oh btw pools are easy to look afer if:
1. Its a salt pool with a self cleaning chlorinator.
2. Sand Filter
3. Every 6 months you put in 2 bags of salt and 500mls of algicide and 1 ltr of acid.
Now we come down to the irritating part... I was looking at some powdered chlorine to give the pool a shock and bring it back to normal. Here was 2 options:
Product A - $25 for 4kg
Product B - $27 for 4kg
Cholriene is chloriene right? Well yes but on closer inspection I saw that A had %50 free chlorine and B had 70% free chlorine... So i spent the $2 more and got heaps more chlorine!
Then for some algicide....
Product A - $15 for 1ltr - 20grams per ltr of copper
Product B - $16 for 1ltr - 40grams per ltr of copper
Product A had almost sold out when Product B was twice as superior! This is why when buying chemicals always look at the active ingredient and see how much there is.
