Just for a sanity check, I decided to take Leslie's Pools up to their monthly free-check offer of my water ... and mostly to see if they get the same results that I just got yesterday doing a full test ... Here's what I was told:
FC = 5.0 -> said that was "HIGH"; suggested to stop putting chlorine in for a couple of days to lower it
TC = 5.0 -> said it was "HIGH" (see above)
CYA = 90 -> said it was "OK"
TA = 100 = OK
PH = 7.4 = OK (I was "seeing" more like 7.5 - that blue test is so subjective though)
Phosphates = 300 -> said it was too high, should be < 100
OK, my test just yesterday sort of mirrored what he saw -- except for the CYA=90 ... once again, I must be really challenged in seeing that stupid dot disappear, because I was getting 45-50 over the last couple of tests. (I can talk myself into 60, but nothing like 90 ...)
Secondly, he confused me saying my FC was too high at 5.0 !! Based on the "tables" of CYA (90) to FC (5.0), I would expect that value to be LOW - and better to be closer to 7.0 - 10.0 .. But based on my own test of CYA=50'ish, I would think my 5.0 would be perfect ... So I am totally confused now.
Lastly - PHOSPhates ??? The TF-100 kit does not even check Phosphates ... Is this something we SHOULD be checking, or is this a sale ploy to get us to spend money??? Adding Phosphates seems to be a bit of an ordeal - running pump for 48 hours, cleaning the filter a few times in a short amount of time, etc.
PS - water looks really clear and nice ....
