Just did my first test for CYA. I am using the 6 way HTH test kit from Walmart. The directions say to fill the tube until the black dot disappears and then read the level in ppm. The last mark on the tube is 30. I was at the top of the tube (just a little past the 30 mark) and could barely see the black dot. I'm guessing my level is around 20 or 25 but cannot be sure because I topped out. Is this acceptable?
Also, my FC is 1.5. Depending on the day (amount of sunlight and/or use) I have to add bleach daily to get the level back to 4ppm. My PH seems to fluctuate between 7.1-7.6 daily. My water is crystal clear (though I've only had the pool for a week).
Should I raise the CYA or keep as is?
