Okay, you got it. I just have a hard time believing I should put laundry bleach in my pool. You all know a lot more about this stuff than I do so I’ll do it. I need to maintain about 3-5 ppm of FC, right? I checked my algaecide this morning and it’s not “poly”. I read what Ben said about only use poly so I won’t be using this junk anymore. I always wondered why you couldn’t just forego the algaecide and maintain it with chlorine and now I guess the answer is yes, you can. Does anyone know if the SWC cells have a life span? Will they last and last if properly cleaned? Or do they kinda start wearing down after a while? Everyone said pools were a lot of work and they hated having them and I didn’t know how they felt until now. Hopefully, I can get everything back in order (with your help) and enjoy this thing again. Another question: (I’ll have them all asked eventually)
Is calcium hardness and calcium the same thing? I saw where Ben said not to worry about calcium in a liner pool. I understand why, but is that the same thing as calcium hardness? I am always adding that stuff – they say it’s our local water.
Anyone here use a sand filter? I am just wondering how often the sand gets changed. The local pool store said I probably have algae growing in the filter. This doesn’t make sense to me because the algaecide/chlorine/whatever flows through the filter so it should kill it.

Thanks again – this place is great,
Brad
