refill - how to start water treament

[fredg]

I have Smart Sticks/trichlor - so I'll probably use them to add CYA - should I also add some directly? Though using them for a couple of years seemed to have raised the CYA through the roof. That was a side benefit of this work, it's all new water so the CYA should be non-existant to start with.

The pool was empty and virtually dry when the contractor finished, so all the acid is out. I'm not sure of the source of the water, but I have a test kit - a real one not strips - and will test what's being put in.
