When buying bleach, check the strength of the bleach carefully. I haven't found any generic brand 6%. Walmart's is 4% and a lot of other stores don't tell you the strength and it is usually as low as 3%. You may find some Clorox in 6% strength.
If they still have it in stock, you can 12% liquid pool chlorine (bleach by another name), at CTC - the Aquaris brand is $4.69 for 5 litres, which is about 1.3 US gallons. As I learned here, if you don't use the 12% right away, keep it in a cool place as at 80 degrees+ it will lose strength very quickly... not a issue this weekend anyway.
The pucks sold at CTC, Walmart, or pool stores like Campbell or Mermaid all have stablizer in them. "stabilized chlorine" is not any different than bleach or other methods of delivering chlorine. It just means that they had included stabilizer (CYA) with the chlorine.
You can buy stabilizer (CYA) by itself, so you can bring up the stabilizer level and use regular bleach.
Stabilizer will break down over winter, so with the weather, and that we are pretty well at the end of the season, there likely isn't a big advantage in adding a lot now.
Ton of rain today, at least 2 inches. Had to drain the pool as the water level was above the skimmer.
