Below is a link to Randy Holmes-Farly's 2-part homemade recipe.
http://www.advancedaquarist.com/issues/april2004/chem.htm
This is a great recipe that I have been using for about 2 months. It has keep my ca and alk levels around 450 and 180 ppm respectively. The only problem so far is the availability of Dowflake. Since I couldn't get Dowflake in Pueblo, I started researching other calcium chloride ice melters, and found two readily available locally. They are Excel (I use this) ice melter, and Preston Heat Driveway melter.
Below is the Material Safety Data Sheet (MSDS) for the two products.
Excel Ice Melter (Scotwood Industries, Inc.)
Calcium Chloride_________________93% Min
Alkali Chlorides___________________5% Max
Magnesium_____________________.02% Max
Other impurities_________________.20% Max
Prestone Heat Driveway Ice Melter (Dow)
Calcium Chloride__________________90-97%
Sodium Chloride____________________1-2%
Potassium Chloride__________________2-3%
Strontium Chloride___________________0-1%
Water
I called Scotwood industries and was told that Excel is 94-97% pure. I also called Dow and was told that Prestone is 90-92% pure.
You can purchase Excel at Sams club for about $17 for 50 lbs, and you can buy Prestone Heat just about anywhere (Home Depot, Walmart, Autozone...) in a gallon jug.
This is a great way to save money when adding the 2-part system, and we have Randy Holmes-Farley to thank for coming up with this recipe.
PS. If you one of the two ice melters above, you should mix it at 82% of Randy recipe using Dowflake.
