The pool was opened yesterday and my first set of results are posted below. I'm looking for advice on where to go from here. I had the pool company add only liquid chlorine and nothing else. I was thinking I would start bringing the FC down as I get closer to getting it clean. The pool was built in OCT '06 and never reached significant CYA levels so that was basically nil on the test. Do I just use pucks to get the CYA up or do I need to do something more immediate?
CYA-less than 20
