The pool season is about to start over here (Canada, QuĂ©bec) and I just opened the pool few weeks ago. Water is now 60F
I have a simple question about Calcium level. I have a 24 feet above ground pool and I'm using a SWG (AquaTrol). I was wondering if I have to respect the Calcium level specified by the AquaTrol manual even if I have a vinyl liner. It says to keep it between 200 - 400 ppm.
I'm asking the question because I sometimes read on the TFP Forum that Calcium level is not that important for Vinyl liner (AG pool), it is more for other type of pool (plaster pool, ...). Am I wrong?
The thing is that the aquatrol SWG is used only on above ground pool, so why would they specify 200 - 400 (for Calcium) if it's not that important? My Calcium level is presently 210, but I'm wondering if I should keep it religioously between 200 - 400 for the whole summer?
