Need help with cloudy water in brand new pool

[chem geek]

Liquid chlorine is the same as bleach except that it is more concentrated. Typically, bleach is 5% or 6% strength while liquid chlorine is typically 12.5% Your SWG should generate chlorine automatically, but perhaps it's not doing so fast enough or perhaps the contractor wants you to add more chlorine to shock the pool. As for adding more chlorine, that may or may not clear up your cloudiness, depending on what the source of the cloudiness is. Nevertheless, you do need to have more than the 0 FC you reported!

Having a vinyl liner (and not having any exposed grout or plaster anywhere) just means you do not need to add calcium to your pool so your Calcium Hardness (CH) will be low or close to zero.
