I've had consistent issues with low alkalinity (2.5 mEq/L) in my 12g Nano, ever since I set it up a year ago.
Recently, the alk dropped down closer to 2.0, so I performed two 50% water changes, hoping to raise it back up. That worked temporarily as it was back up to 2.5 for a week or two, but it has since dropped back below 2.0 again.
Since my other two tanks are consistently around 3.0, my question is what could be depleting the alk in this tank?
Its a 12g nano, with ~1" of aragonite, 10 lb of LR, 2 ocel clowns.
Filtration is 2 sponges, LR, and chaeto. I've replaced the stock filtration with a MJ600.
I've had a consistent hair algae population, but my coraline is quite prolific as well.
