Water got away...trying to catch up

[jojasc]

Well I think I caught up with my water. I believe that the algae is under control, now the only issue I have remaining is that the water is cloudy, which based on what I have learned from the forums is probably due to my high alkalenity. Here are the test results from water test I just completed.

FC: 17.5
CC: .5
TC: 18.0
pH: 7.8
TA: 200
TH: 350 (I seem to get inconsistent results with this test?)
CYA: 70

My plan from here is to continue to add chlorine to maintain shock level of 20ppm for at least one more day, adjust my pH slightly downward and then close the pool. Based on reading replies other posts it seems that it is OK to close with the cloudiness due to the high alkalenity levels and adjusting in the spring. Or should I use the lower the pH and aerate the water method to lower my alkalenity prior to closing?

Last question (for now). In using the "black dot" method to test CYA in the K-2006 test kit, could anyone shed some light on their opinion of what "just disappears" looks like as the directions indicate? This seems to be somewhat subjective in interpretation. Maybe I am being to nit picky as I try to learn....

Thanks all for your help.

The cloudiness could simply be dead algae suspended in your water. Remember that the chlorine kills the algae, but the filter has to get it out of the water. Keep your pump on for the next couple of days and brush the pool daily, and see if that helps clear it up.

The CYa test is very subjective, it only really gives a close ballpark....the key to consistent results is to run your tests consistently every time...test in the same place, same light source at same intensity, etc. Then what YOUR interpretation of "dot just disappearing" is is what you do every time.

congrats on getting your water back under control again....
