Hi, I'm a beginner at pool chemistry and I have a 12x30 Intex EasySet pool. It's only half full, so I am using a pool volume of 850 gal in my calculations. (I know that's teeny, I have toddlers.) I'm in the Pittsburgh area.
I want to follow the instructions in the Beginners Guide for Seasonal/Temporary Pools on this site. It says to buy a "drop based test kit that tests for at least pH and chlorine" so I bought exactly that.
1. In step 5, it says At the end of four nights, your CYA level should be around 30. How do you measure the CYA level with that kit?
2. The chemicals the pool store gave me are Balance Pak 100 Bioguard, Balance Pak 200, and Shock and Swim. (Eventually I want to switch to the household chemicals once I use these up.) I added too much Balance Pak 200 and the Cl is 0.5 and pH is now 8.2. Can I lower pH using just the chemicals I have, or do I need something else?
Thanks, all. Sorry to be such a noob but we all have to start somewhere!
