My Aqualink RS system gives me pool water temperature. I happen to have a floating thermometer but have not needed to toss it in the pool.

Turned on my pump and it says 92 degrees for the pool water. Updated pool math.
Lower your TA to 60 or 70 and your CSI will become negative. Or you can test your salt and add 1000 ppm to 2000 ppm of salt to lower your CSI.
So dont use baking soda? Use acid to lower PH and then turn up pool jets to aerate correct? First I have heard of adding salt to a pool...if this is a good option I am not opposed to it.
To go from CYA 90 to CYA 40 you would need to drain 56% of your water.
Restested tonight and my CYA was 50. Maybe I didnt go enough yesterday on my test. Today I went until I could see no hint of dark circle.
Shock and mustard algae FC levels are given to you for reference in case you need them.
You need the
SLAM Process if your water is cloudy due to algae or you fail the
Overnight Chlorine Loss Test
What is your question about plaster?
My question about plaster was do you or anyone see anything that would suggest my plaster is being damaged or that I got a bad plaster job? or are these discolorations normal? They dont seem normal and have gotten worse IMHO.
Have you read
ABCs of Pool Water Chemistry?
Yes and rereading over and over to sink in. Thank you for the help so far.
