Drained and refilled - adjusting alk and calcium

[duraleigh]

I don't think there's any rush to adjust Calcium. It certainly needs to be brought up but I doubt there's an immediate need to get it done.

If you're planning on keeping the pool open for a while, I would suggest keeping the chlorine up into 2-5ppm range and adjusting the pH as the first two priorities. You could put 2 pucks in each skimmer and perhaps get your Cl up, add a little CYA, and control your pH all at the same time.

The pucks will not give you much CYA if you're staying open all winter so you'll need to buy some seperately.

Along that same line, Cal Hypo would chlorinate for you and add calcium but not enough calcium to make much of a difference so you'll have to add that seperately as well. I think I'd try to move the Calcium maybe 50ppm at a time instead of try to get to 200-400ppm all in one dose. I believe you can add it whenever you like over the next couple of weeks or so. Again, I am not aware of any reason to rush it into your pool.......keeping your Cl and pH in line would be my first step.

PS - I think you're gonna need a whole lot more baking soda. Did that three pounds make much difference? Bleachcalc tells me you needed about 35 lbs initially. What are you using to test?
