I have that thermometer! I thought it was a "steal" @ $12! =) Yikes, that is a bit chilly! Our hasn't been below 80/79 for at least 3wks, even with all the storms we've had (to cold for our tastes still, bit it bumps up quick in the sun, since it's tiny)So jealous of these temps in the 80's! while picking up chlorine at wally world the other day I saw a neat little floating digital thermometer that I HAD to have. However all it has accomplished is to quickly let the rest of my family know that it is no where near ready for them to entertain the thought of getting in the pool, at 67 degrees! LOL. Last week we had a few warm days in a row and the temp actually crested 80. But it's been rainy and mild the last several days and that sends the temp plummeting. Time for a water heating strategy.
