Chlorine Loss Jumped

[Mickey Moose]

A 30-day chart, oldest at left. Notice yesterday's test where Chlorine loss crossed above FC. Average daily loss for the 30-day period is 2.4, with the highest being 3 until yesterday's loss of 4. Nothing was seemingly out of the ordinary with the last two days. Weather has been the same, no debris in the pool, pool wasn't used, all other test are normal. I'll post a follow-up this afternoon after testing.

Today:

FC: 5
CC: 0.5
Loss: 2

...normal.

I wonder what caused the fluke yesterday. I measured twice due to the oddity and got the same result both times.

Oh well.

That is odd ... perhaps some biologic substance got dropped in the pool. Birds dive bombing

If, at the time you sampled, the pool had not been circulating for a while, you may have got a suppressed FC level due to your sample not being from homogeneous pool water.

Good point, though not the case. I test in the afternoon - typically 4 - 6 PM... pool has been circulating since 8 AM. In addition, I always get my sample from the same place, including depth.
