like jello - that's it !!!
Thanks for the replies freshegg and ayesr! That's a good and exact description of what I felt. Partially set jello!! If not for our distance, I'd bet you had been there Sunday. Glad to know it wasn't just my wife and I that experience this.
And ayesr may be close to the cause. I left out information that it had rained Sunday morning. Also the main Canadian National rail line into Halifax is about 100 feet behind the location of the photograph of the pool. So there are lots of pollutants available near by - not to mention the nearby highway.
I'll be more observant in the future of the weather conditions near swim times and what the water feel like. They also have birthday parties at the pool so I'm also not ruling out the jello factor !!
