Some quick help, if possible

My alkalinity was too low on my tank and coralline started bleaching. I was at 6.4 on 10/8, 6.1 on 10/13. I began dosing AFR (5ml on 10/18, 7.5ml on 10/19, 2.5ml on 10/20). On 10/20 I tested 7.4 in the morning, 7.6 at night. On 10/21 I tested 7.6 in the morning, 7.8 at night. I dosed 5ml this morning.

How true is the 3 day rule for testing, or at this point will alk show a quicker change w/ AFR ?

Edit: 25g AIO, 2 months old w/ live rock. Low coral stocking. Still figuring out daily consumption

Have you calibrated the device you use to check salinity? If you have not, and you think you have 1.026, but really you have 1.020 or something similar, then your alk and calcium will be low, as you have indicated.

Your tank doesn't have much to be using alk and calcium, so if both of those are low, with no LPS/SPS then something isn't adding up.

I’ve been sitting at 1.026. After dosing I’m starting to get more consistent readings

Yes, you said that, but what have you been checking your salinity tester against to verify that. You THINK you're sitting at 1.026. You may be. But if you don't calibrate your refractometer, you don't know.

I will test at LFS this Saturday, then get water if needed

I have two small, small, mushroom corals along with a single small leather. I then have Coralline on the rocks which started to bleach. Would these consume alk and calcium?

My reading for Alk is now high 7's, with Ca at 450.
