Went on a quick trip over the weekend; used the motel pool. The water was cloudy and greenish; the equipment looked pretty new and included an inline chlorinator (tablets, aack!) Excessive CYA, I don't doubt. There were sufficient bugs floating in the pool to motivate me to fetch the skimmer net and scoop them out.
Yes, I did get in anyway! Wore a swim cap and took a shower with soap afterwards.
It was great to get back to my own sparkling clear pool! I know I'll never look at pools the same way again. Every time I see a pool that looks less than perfect I want to get my test kit and get to work.
