I have been posting as a new member (and new pool owner) in a different thread about what a mess my pool is in.
I purchased the required testing kit, tested everything (twice) and it has been determined that I have virtually no chlorine, green algae starting to grow and very low pH.
Before I can go through the recommended shock process, I need to raise my pH.
My water tests below 6.8 (how much lower I can't tell because the chart only goes to 6.8 but it is at least one shade lighter than 6.8)
Over the last 24 hours I have added 10 lbs of sodium carbonate (5 lbs at a time) let it circulate for a couple of hours and re tested after each application.
The pH remains below 6.8.
What am I doing wrong??
