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.

You can use the trichlor but just monitor your CYA so you can quit using them when you get CYA to 40-50. But, it will take a bit before they get some CYA in there so for a few days, you'll probably need to keep an eye to make sure you have chlorine in there. Or, your other option is also ok, use a little CYA to get to maybe 20 or so and then use the trichlor to get the rest of the way to 40-50. Any way will work. Just have to monitor things. Also remember that trichlor is very acidic so it will push your pH down. Have to watch that, too.
