At the pool store. You shouldn't be using that many of them. The discount for buying in bulk is not worth the headache of storing them. Just pick one up at the store when you need it.
Hey neighbor,
Three degrees sounds about right for this time of year and the fact that it was partly cloudy all day. I don't even bother using my solar this time of year. I mostly use it to extend the season into March and November.
True. Although if their ph really is 8 and ta 150, it should be pretty close. Hard to use a pool test kit to know 8 ph from 8+. Just chiming in to mention that the ph effects of cya should be taken into account.
Thanks for the welcome. I've been a long time lurker. Lots of good info here.
