your advice needed for test results

Thank you .
What is "washing soda"? Is there a specific product name that I should look for in the grocery store?

You can find it at the grocery store as Arm and Hammer Super Washing Soda in the laundry aisle. It is EXACTLY the same as pH increaser from the pool store...just cheaper! Just be cautious with it. It will raise your ph fairly fast and will also cause your TA to go up.
