Re: ph low
Hi Timmie,
Your pH at 7.2 is in the acceptable range--I wouldn't mess with it unless you have problems with it falling. Are you using trichlor pucks to chlorinate with? Your CYA is awfully high, indicating that you are either using trichlor or dichlor, both of which will drive your pH down. If you switch to plain bleach, you'll find that your pH will probably rise a little on its own. I do suggest that you don't use either trichlor or dichlor at this point, because they also drive your CYA up, and it's already very, very high.
Just another comment, with your CYA at above 100, then you need to keep a MINIMUM of 8 ppm chlorine in the pool to keep it sanitized, and can safely keep it as high as 15 or so. So your 9.8 chlorine is fine, and should not cause stomachaches. If you lower your CYA , then you can safely lower your chlorine levels without algae blooms, but this can only be done through partial drain/refills.
How often you need to add bleach to your pool depends on your bather load, other "stuff" that is introduced to your water, and your cya and beginning chlorine levels. Obviously the more chorine that's used, the more often you'll have to add, but that tends to be different with each pool. I personally suggest that you take the time to test for chlorine daily, adding more when you find your levels at 8 or below. It won't take long for you to develop a feel for how often you're going to have to add it.
