I never bother telling anyone what I put in my pool, so haven't heard any negative remarks :-) I have had store clerks give me the eye when I buy large quantities of bleach. I have one friend who is aware of how I treat my pool. She is putting in an in-ground pool this summer, and I have no doubt she will have a pool service start up her pool and probably do weekly maintenance. If she ever asks for my help I'll give it, but until then I'll stay quiet. I just don't have the energy to try and convince anyone I'm right. I KNOW I'm right... lol.
