Emergency... mistake while dosing!!!

[fresh]

Hi all,

So this is my first time dosing Ca/Alk and I made a biiiiiig mistake!!!

After I put one (LARGE) cup of Calcium Chloride mix that I just created and one (LARGE) cup of Baking Soda mix that I also just created, I measured both Ca and Alk to see where I am sitting at.... My reading were 550 for Calcium and 19 for Alk!!!!

How bad is this? How can I solve it? Is it ok to leave the system as is until these two get depleated?

Will this kill any of my animals??? please let me know.

Thanks
