I think my test results are visible, please let me know if they're not. I did a pool water exchange a few weeks ago to reduce CYA and my CH dropped from 450 to 275. 275 is just above the minimum but outside the recommended range. Would you recommend that I increase CH to 350, or leave it as is? We resurfaced the pool about a year ago, in case that makes a difference.
On another note, I've read different things about using MA. I generally let pH rise to 7.8 or 8 before adding MA. I've seen guidance saying I should only add it a quart at a time. Is that reasonable? The most economical MA for me is 14.5%, so it's fairly weak as MA goes. I slowly add it in the deep end so that it gets distributed by the jet there, have the filter pump running, and then do some brushing to make sure the MA doesn't "pool" in one spot. Any thoughts on how much to add at one time? pH is at 8.2 today, so I will be adding a gallon of MA total.
Thanks for making this site available, it's a great resource.
