Jimmy,
I didn't read close enough... the CYA should be zero in fill water so wait a while. I am not familiar with the HTH test but you can always have the pool store test for CYA. It will probably take a week or so of the pucks to get the CYA up to min levels so just check the level at that point. Until then you WILL have a tough time keeping chlorine in the water. Once you get the equipment hooked up I would dose with bleach to shock the pool, about 10ppm. This will take approx 2 gallons of regular bleach - 1 gallon 5.25% raises 10,000 gallons to 5.25ppm Cl.
