Backup Trichlor tabs

[Sam8407]

Will be going on vacation with no local help on adding liquid chlorine. I know the Max Blue tabs are a no no. “Other ingredients” in these are only 1%.
Think I’ll be safe with these and just deal with a partial drain of the cya gets too high?

Thanks!

How long will you be gone? The tabs will help for a short time, but it's crazy hot in TX.
