Hey, I just dosed Brightwell code B and was wondering how long after dosing should I wait to test alkalinity?
Thanks

General rule is 30 minutes..but it depends on your flow

Wondering the same question. I thought I needed to dose 15ml per day but for some reason my ALK dropped 0.1 two days in a row. So I am thinking I might dose, wait 30 min (probably an hour) and test and see if my dose brought the tank to my target at least...
