So I am not sure what happened recently. I dose AF Component 1+, 2+, 3+. While testing yesterday I noticed my ALK had dropped, while all my parameters were within range. I have Kalk, but did not want anything else to swing, since everything was within range.
I ended up confirming my ALK with a different test kit, and same thing. Took me a minute, but I remembered that I normally buy pure sodium bicarb in bulk for the pool to raise the ALK. Did a little bit of reading to confirm, and boom. Household fix to my alk problem.
Now, seperate issue. Time to figure out why my alk swong so much. I think it might be the coralline?
