Just stumbled on to your site bout a week ago after the pool store employee (little girl behind the counter) told me I needed to empty my pool and replace with fresh water. Thank you Thank you for this web site. Lots of very useful info. I now have been schooled on CYA.
Here are my numbers. Question-I have now removed and replaced about 6 inches of water 3 times. I know from this website not to completely empty pool but what is the safest amount I can empty.
Adjusted Alk-75 by the way which one do we go by?
