If you keep the water chlorinated, it won’t get funky. (years ago had a swimming pool) In fact for not too much money you can get a kit that tells you when your chlorine is low....(sorry if you already knew that) :O)
Well, I’m way past worrying if it is funky. Haven’t used it for swimming for about 5 years. The funk just sinks to the bottom!! It also occurred to me a while back that if I were to have a fire here, it would be useful for that, too, so I’m just going to let it sit.
I’m enjoying reading all the great info here, aren’t you? I’m learning a lot, and getting a lot of good ideas.
