Yes that is what I am leaning to, just afraid I will go to far so since my kit only goes as low as 30 I know its less than that. I will say it is at 20 and I want to go to 40 so from the poolcalculator it says I should add 138 oz of liquid or 56 oz solid. I would prefer liquid.

So do I pour it straight into the skimmer( or dilute with pool water) or throughout the pool? Since my Cl is low should I chlorinate or stablize first? I was thinking of chlorinating tonight and then stabilizing in the am. Any thoughts?
