We are now into the hot part of the year. The pool is at something like 90 degrees now. Still refreshing when it is 97 or 103 outside but I'd like it cooler.
I noticed on a local Weather bug site has a link to the graphs of all the collected data, looks like minute by minute. While we had been having cool temps in the evening, back in May when I set this time schedule up, that is not longer the case. The air temp does not get below 85 until midnight on average. It stays below 85 until maybe 9 or 10 AM, then it rapidly climbs to 98 or better.
Back in May when I set up the current schedule, it cooled down by 4 PM and so I ran most of the filter time after 4 PM and then again in the morning before 11 AM while it was still cool-ish. And I ran the waterfall at 7 AM and 8 PM, when it was a bit cooler and when I could enjoy seeing it. Now 8 PM temps are still about 93 degrees, just too hot.
So, I am going to reset my filter times to run primarily overnight, between midnight and 10 AM when air temps are below 85, then one hour every 4 hours just to get chlorine circulated into the spa. By September things will start to cool off again, mid September. But what I was doing did pretty well until this last week or so when the nights got so warm.
I'll give it a few days and see if that makes anything any better.
Now, is midnight 12 AM or 12 PM?
