1. Get a cheap local OTO / phenol red test kit (yellow / red drops) and USE it.
2. Start adding 20 Mule Team Borax, 2 boxes at a time (slowly, via the skimmer, pump on). Wait 1 hour, test, repeat till pH 7.0 or above. If you can't find borax, buy Arm & Hammer Washing Soda (soda ash = pH UP) and use 1 box at a time. Both should be available in the detergent section of Walmart or many other stores.
Try to find borax; besides raising your pH, using it will tend to immunize your pool against algae.
3. Order a K2006 test kit; in Canada, I think these guys may be your only source: http://piscines-apollo.com/index.html Report back as soon as you know your CYA level.
4. Do NOT worry about your alkalinity or calcium levels.
