How much daily chlorine to add temporarily?

[McAlsop]

I have a 400 gallon hot tub. Everything is balanced and it's set up based on the pinned Bromine hot tub post. The bromine tabs (spa frog inline) are out and it's inaccessible until a new part comes in the mail (1-2 weeks).

I'm just hoping someone can suggest an amount of chlorine (Swim Shock 12.5%) that I can put in daily or twice daily to keep it in good usable shape until I get the replacement part.

I have no basis to estimate an amount. Usually I just put in about 1/2 cup weekly to shock as it suggests in the pinned post.

Thanks for any help!

Post a full set of current test results from your TF-100
I see your last (and only) entry in PoolMath is 3 years old and for your pool.
How old are your TF-100 reagents?

If “swim shock 12.5%” is liquid chlorine
here’s what 1oz will do

This may or may not be enough depending upon where you’re starting from.
