My friend has suggested to me that I purchase 3 "big buckets" of calcium hardness. This will be new fill water. It will also be a vinyl lined pool, which I have read here, does not necessarily require CH "maintenance".
Factors of our pool include direct sunlight from 8am-8pm and we will have a SWG.
I just placed an order for my liquid stabilizer and if I need the CH, will try to get them to tag it to my existing order before it is shipped.
