I have been trying to locate Calcium Hypochlorite that has at least 75% and I cant find it anywhere. I was told at the pool store the manufacturers were reducing the % available because people were using it in the wrong pool and damaging the pool liners. I also went online to Leslies Pool and the % is very low. Is there a company who currently has the higher %? Also, in the book it says not to use any low %, but in other places he doesnt mention it or he says to double the amount of a lower % to equal 80%. Help! What to do? Thank you!

Hi Jane,

Here are links I have on MMS2:
www.lesliespool.com/Home/Pool-Chemicals/Pool-Shock/14676.html . Leslies pool supply is a national chain in the US, get their product in the link “Power Powder PLUS”. They have two products "Power Powder" and “Power Powder PLUS” so you want the PLUS which is a higher percentage. Regardless of what the websites say, it is 73% calcium hypochlorite on the label when you buy it; this is what I use. About $5 for 1 lb.

The highest concentration of cal hypo in a pool shock that we've seen in the US is 78%. Google "POOLIFE Turbo Shock" and you'll find distributors.
www.hydropool.com/cgi-bin/hydro/item/HTH-POOLIFE-TurboShock-78-1-lb-bag-Pool-Chlorine/22405.html One place to get 78% pool shock.

The Leslies pool shock is 73% calcium hypochlorite listed on the ingredients label; on websites they sometimes have an "available chlorine" percentage that is less than 73% but that is NOT the calcium hypochlorite content. Apparently the Poolife Turbo Shock is 78% calium hypochlorite AND 78% available chlorine. These are just labeling differences amoung manufacturers. I will attach a copy of the Leslies label so you can see for yourself it is 73% cal-hypo.

The Leslies works fine at 73%, I just bought a bucket of it. My friends and I have been using it for a couple years. I don't know if the the Poolife turbo shock is available in my local area, at least not as easily as the Leslies.
