My pool hazed up slightly last night after a pool party, so I assumed that similar to another recent post, I had an increased biologic load in the pool, from the extra swimmers. I added 2 extra ppm last night to the usual dose of Cl, and the water looks better this morning. I can't even tell if the water has any haze left or not. That's easier to tell when it's sunny.
My question is this: I can't seem to get a consistent number when I use the fas-dpd test.
For example, last night I got:
I added 5ppm Cl after testing
This morning, results were:
10.5, .5<cc<1.0(took 2 drops to clear)
I try to be very precise when I run the test. I follow the extended directions to the letter. The only thing that is hard to keep the same from test to test is that sometimes I end up using a scoop of powder that seems to be all powder, sometimes there are a lot more "chunks" in it. (I warned you this question was nitpicky! )
I can't decide from all these results if I need to go through the shock process or not.
(This was not a true oclt since it was already fairly light outside when I tested this morning)
Btw the swg in my signature is not turned on right now.
