Just looking for input.
I didn't test yesterday but I just tested and my FC is low. It usually runs at 5-5.5, and that's at the lowest setting (20%) on my SWG. My results are
FC 0.5
CC 0
PH 7.4
TA 70
CH 180
CYA 35 (working on getting that up)
So, that big dip in FC got my attention. I turned the filter back on, turned the SWG up to 40% and added 2 lbs of 65% Cal-Hypo. (Since my CH runs low, I keep that around for emergencies instead of bottled bleach.)
I'm thinking that this happened because of a combination of the series of sunny days we've had and my husband leaving the hose in too long yesterday, replacing evaporation. The water was just below the arrows on the skimmer and when he took it out it was above the skimmer. Evaporation has brought it down to just below the top of the skimmer today. Our fill water is bland, no chlorine, 7.0 ph, no CH, no metals.
If things aren't perfect with the water tomorrow I'm going to do a OCLT tomorrow night.
Water LOOKS perfect.
Would you recommend anything different?
