Alk Dosing

[ajoe]

Evening all. Just started dosing 2 part BRS Alk last week and have gotten it up from 108 ppm to 138 ppm slowly and efficiently but seems to stall out there. Reef calculator calls for 21 ml but after adding and re-measuring an hour later unchanged. I am wandering if my RODI top off of 1 - 1.5 gallons p/d is diluting it and if so what would be a safe dosage to get it to 150ish. Trying not to raise it more than 25 ppm p/d but seems like a revolving door. I know it takes a while to dial in but seems like it is loosing the amount of ALK p/d that is required to reach my goal of 150.

50 gallons of joy.

Where's your magnesium?

What all is in the tank? U can safely increase alk by,1.5 dkh daily or more if there is no livestock in tank. Also if there is livestock it's common to see 2-4 dkh consumption daily.
