The water is three months old; however, its usually just my wife and I that use it once a week or so. My older daughter did use it a couple of times with a friend each time.
OK, so I really need to drain it for piece of mine anyway but do I need to disinfect it or did the 8TBSP of dichlor kill everything?
If I have to drain it completely and disinfect it, I'm probably done for the winter because thats not something I'm willing to do in the temps we have been having this winter.
