HELP: Overdosed Reef Fusion 2. Alkalinity is way up

[Frogspon]

I've been trying to get my doser set up and it unfortunately emptied about 100 mL into my 75 gallon tank over 2 hours.

Lights are off, everything seems fine ATM but my Alkalinity is way up to 11+ (normally around 7.5 with lights off.)

What should I do? The salt I use has 11 dKh so I don't think water changes would be beneficial.

Thanks

It may be too late, but you could try adding vinegar to lower it.

Vinegar is not a solution to high alk. It only delays the high alk until the acetate is metabolized by bacteria and other organisms, which might be only a few hours.

I'd just let it slowly fall on it sown if the alk is not above 13 dKH.
