Re: Help converting from Shock and Sticks
You will need a complete set of numbers but I'd bet your CYA is very high which is why the 'shock' products are no longer helping. You will have to either run a higher chlorine level to accomodate, or drain and refill the pool to dilute CYA down to 30-50ppm.
The BleachCalc is set to do multiple types of calculations depending on which variable you supply. Usually you enter figures in -some- of the white fields and the answers are shown in the grey. For example, if you want to know how much X% bleach to add to Y gallons to raise chlorine Zppm, you enter those three variables (X,Y,Z) and hit calculate to get the answer.
Be sure to first go to MoreCalcs>Settings and set it to Imperial to get US gallons. Also note that it will calculate the water volume of your pool, a number you will need for everything else.
As to the desired readings, you need a combination of this post and this one to get a quick explanation.
