Do I need to get base-demand and acid-demand reagents to do this? Do I need a complete kit, or can I go to the pool store and just look for Taylor reagent refills to accomplish what I want?

Also, if I can assure I am actually at 8.2, are there any comments about running my pool this way on a permanent basis?
