Being in Nebraska, the temp at night is really starting to drop, so I bought a solar blanket. It does a great job of reducing heat loss at night as well as reducing chlorine loss during the day. I faithfully test the water every day, make adjustments and keep everything in range. This week we had the cover off and swam on Tuesday evening. I left the cover on continually from Tuesday night until Saturday morning and when I took the cover off, there were dozens of backswimmers. Numbers this evening, after a day of bright sun:
FC 6.5
pH 7.2 (I recently added MA to bring it down from 7.8 and the blanket also slows the pH drift)
TA 70
CYA 50
I saw a backswimmer fly out of the tree and into the water as I was scouping them out of the water with the net. If that dang solar blanket creates a breeding ground for backswimmers, I"m not going to use it.
Is there anything I can do to avoid this problem and still use the solar blanket? I was hoping it would extend the swimming season.
