Lower alk with muriatic acid.



Calculations for figuring out dosage...


water volume x DKH drop x 0.123 = amount to add in ML.



Example:

25 gallons of water, 2.5dkh drop x .123 = (this is my typical calculations for my 25G brute)7.68 or in my case I would just add 7.5 and test. This will usually take me to just around 8.5DKH.


Just keep in mind that the PH will drastically fall when adding the acid. Let your SW mix for another 24 hours before using to bring the PH back up.



And for the love of all things salty, under no circumstances should acid be added to a running system.
