Oops.

I forgot to include the info that my Alk has dropped a lot in the last two weeks: from 9 to 7. I'm worried that it is going to continue to drop.

Everything else has really stabilized in the last two weeks. I've backed off on my water changes (doing fewer and less volume) and that seems to have really helped. My mag is still a litter lower than I would like to see, but it has improved (raised) quite significantly.

The improvement in this tank is crazy . . . considering what I've done to it. It is heavily (and temporarily) overstocked right now, as I shut down my Nano Cube due to temperature issues and moved everything into this one. One of the critters in the tank is being very heavily fed, too. It must have 4x the bioload that it should.

If my alk continues to drop . . . at what point do I panic and intervene?
