Sodium Bicarbonate by mistake

[GSP]

Hi:) In trying to lower the TA I mistakenly added Sodium Bicarbonate instead of Bisulphate......what can I expect to find in the morning and what can I do next to fix it?? Thanks...new to this pool business

You can expect to find your TA higher. If other parameters such as pH and CH are also high, then you might see some scaling (lowering the pH should remove it if it's fresh). You can lower your TA by acid addition along with aeration at a lower pH. Follow the procedure in this post. By the way, why are you using dry acid (sodium bisulfate) instead of Muriatic Acid? Dry acid increases sulfate levels so if you use that frequently that can be detrimental to plaster (see this post).
