I have been in SLAM process for over a week with little results. Pool still not clear at all. 4 ft pool 14000 gallons and can only see down about 2 feet but it is blue, not green. Combined chlorine has always come up .5 or less. Today I did the test and put in R-0003 from the TFT-100 test kit after figuring out my FC and it was clear or less than a drop would have cleared it. I then finished eating and forgot to dump the water so then about 10 minutes after completing the test the tube has pink water... do you have to wait awhile after adding the reagent or look at it immediately. Does letting it sit give false positive?
CYA high -80 so we have been maintaining a chlorine level of 31 and starting to run out of drops and getting frustrated.
This is a new house to us and not used to pool. We live extremely close to a flour mill. Any chance it is dust and too fine for our sand filter to really get it out?
