Over the past month or 2 I've been experiencing the very strange phenomenon of my alk rising without me dosing it. I have a theory as to why that I'd like to run past you all.
I reintroduced a decent amount of sand that had been siphoned out of my tank from a while back, that was stored damp and loosely enclosed. I'm wondering if during that storage time the pH in the bucket dropped enough to partially dissolve the sand. I did rinse the sand thoroughly before reintroducing it, but maybe it's releasing carbonate in the water now that it's been reintroduced.
Does this sound like it could be the cause?
