In Rochester NY we're still swimming as of Oct. 5 and we'll use the pool this entire weekend since the Wx will be sunny and in the low 80's!

I've been heating with gas on days when we plan on using the pool to get the temp back to 84. The temp has been holding well in the mid/upper 70's as we keep it covered and I do keep the filter off all night which really seems to help. I've have noticed the sun is definitely loosing strength because I'm barely seeing any temp rise from the sun.

First swim was May 9th this year, so we will have 5 months of use... a great year for a pool!
