    Cost to Shock

    Just replied to another post regarding cost of chlorine and decided another chart I made last year may be helpful to others. I got the impact of chemical use and qty to move FC from the Pool Calculator. At the time I didnt realize you didnt need to shock weekly but its still a quick snapshot of costs.

    You do not need to shock weekly, you only need to shock when water testing, water appearance, or unusual incidents indicate a need to shock.

    There is a very through comparison of the cost of various chlorine sources in this post.

    .............and to add, if the (CC) level is above 0.5, or the free chlorine (FC) level is zero.

    Re: Cost to Shock

    At the time I made this side-by-side comparison I wanted to see for my pool the costs and corresponding FC move per bag or jug of chlorine. This way evertime I needed to shock I knew exactly what I was getting into using the available options.

    Didn't know other post existed, very detailed analysis thanks for the link. Also didnt know about BBB and the rules of not needing a regular shock if you keep your FC in balance.

    I have to give credit to Jason Lion for the chemical multipliers for the FC change and corresponding changes in other balances depending on the method of chlorination:
