If my math is correct, 6 96 oz containers of bleach = 4.5 gallons, which will raise the FC in a 36K gallon pool by 7.5 ppm, which is not nearly enough to clear up an algae bloom. Each gallon of 6% bleach in a pool that size will raise your FC by 1.7 ppm, and with your high CYA you need to get it up to (and keep it at) 25 ppm.However, you need to take a look at your well water analysis before you do this, because if you have metals in the water, then raise the chlorine that high, you may end up with a tea colored pool. So post your metals analysis here before you shock the pool!

The hth kit is not hard to use, but you'll have to force the chlorine test to read higher than it's supposed to by diluting your sample and multiplying (see this thread http://www.poolsolutions.com/gd/how-...d-testkit.html). That's why you need the K-2006--it will accurately test chlorine levels to at least 50 ppm without guessing.
