Thought I said it too!!
Anyway, back to the questions.... 1.5 gallons of bleach in a 22000 gallon pool actually should raise your chlorine by about 4, and you don't even achieve shock level with a CYA of 60 until you get it up to 20 ppm, so if you're still trying to kill an algae bloom, you definitely need to go ahead and add the bleach per Pooldoc's instructions, and try to maintain the 20 ppm by adding chlorine as often as you can during the day in order to kill off the bloom. The filter running 24/7 will remove the dead algae from the water, but the chlorine is what will actually kill it.
You can get CYA at WalMart, in the pool/spa section, or at the pool store.
How much Borax it takes to raise pH by a certain amount depends on your TA level.. The higher the TA, the more Borax it will take to make the pH move. Somewhere around here there's a calculation for it, but I'll have to search for it and come back to edit this post...
