Is there any rule of thumb regarding expected test results after a day of heavy use?
We had a lot of friends over Saturday and a bunch of teenage boys jumping and splashing around for several hours. I tested the water the next morning and found that my FC went from 8.0 to 5.0 and I now have 0.5 CC where I had none before.
I assume that the heavy use and tracking of grass clippings are the cause of the changes and I'm not real worried.
One other thing...my CYA has been well below the TFT100 test jar reading ability, but finally I can see the dot dissapear at 23!!!!!! Took 2 weeks for the CYA to show up in the water. One more bottle to go.
