Thanks.

That's wayyyyy to much!
It only takes 1/11000th of the water volume to drop the Alk by 2.8dkh
You can thank Randy Holmes Farley for that equation (look up "lowering alkalinity with acid" on RC post #3). So if your tank is filled without rock and is 105 gallons (397 litres) you'd need 1/11000th of that volume which would be 39.7ml to lower the dkh by 2.8. I'd first figure out how much water you have and what your Alk is for the new water then go from there.
