Fill'er Up

Well when I got back from a visit to the college, about 4 p.m. I went out and checked the system. It was at CF=28 (some of that might be temperature correction?? -- the Dipstick is temperature corrected but that's up from the morning). I decided to top the pool off to overflowing so I ran water into it until it overflowed the side and then added 3/4 cup of nutrient concentrate. A quick look seemed to be CF=24, but I'll check when it reaches equilibrium and now we'll see how rapidly it goes down.
