So having read up on which chemicals I should have for my new aboveground saltwater pool (it hasn't come yet, I'm stocking up before it gets here) I'm still pretty confused. I know I need stuff to control the ph and alkilinity levels, shock, stabilizer, calcium, something to control the metals, and obviously pool salt, but I can't seem to find a kit that has all of these things! (Not including pool salt, ill of course buy that separate) Even the most inclusive one, (Saltwater Pool Chemical Kit - Pool Opening Maintenance Kit) seems really pricey and doesn't even have calcium hardness in it! Anyone have advice on buying chemicals? (Especially where and how much I should pay?)
