so I got busy with work and found out the liquid in dosing containers ran out ( at this time alk was 11), so I did a 30 gallon water change ( my total system volume is 80) yesterday and when I checked the alk it was 9.5, I left it with out dosing thinking that the alk would drop but today when I checked the alk is 12.5. Can someone please advice how I can get my alk down. I would like to set my parameters as before alk 8~9 and Cal 430 ~ 450. I’m using Hana and yes the reagent is not expired.
I use tropic marine pro salt btw.
