On the bottom of my pool has a brownish dust on it, when I vacuum or get close to the vacuum it disappears. After I let the water filter it settles back. What could this be?
The pucks raise the CYA level, which may or may not be a good thing. The "shock" could be adding more; there are at least three different powders that are called shock and two of them do. They also mess with the pH. In brief, you might be making a bad situation worse. Anyway.... the solution remains the same as before I can't improve on the answer you got before.I use 'pucks' for right now. I just added 2lbs of shock and 2 3' chlorine 'pucks'
If you believe those strips, your CYA is 50 so your minimum FC should never dip below 4 and you should target more like 7 every day. Your CYA will be slightly higher when those pucks are done dissolving, so 8 FC might not be a bad target for you. Pool School - Chlorine / CYA ChartI have the Aqua Chem 6 way test strips for now. (I know better test kit) but anyway my results are
total hardness-100
total chlorine-0
free chlorine-0
pH-7.2
total alkalinity-120
stabilizer-50
So do you know what I need to add? The water is blue just slightly cloudy.
