Mix completely with the spoon

1 gallon of plain 6% bleach will add about 8 ppm of chlorine to your pool; start dosing with TWO gallons, each evening, till the green is gone.

Usually, you don't have metals in well water when you have high pH + high alkalinity + high calcium.

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.

Hi if I get the 4% one do I just put more in the pool or do I need the 6%?

Thx

[PoolDoc]

4% is fine; just add 1.5x as much.

Is 4% the more common strength in Canada?
