Don’t use AFR to raise you alk/calk… use a two part of your choice to raise, then use AFR to maintain… you’ll have way better results in getting your numbers where you want them and you’ll actually have more success in keeping them there. Just my experience, and what the directions for AFR say to do …Just finish testing my alk again stuck at 5.4 just dosed with all for reef let’s see if it changes tomorrow
And ummm…
