Things continue to go badly, with almost every coral in the tank now showing signs of decline. I've lost two or three colonies completely...As usual, polyp extension is great, even as they die!

However, I think I may have found something. Oh...how I hope that I've found something.

I've just noticed that my pH is not even making it back up past 7.9 at the peak and dropping to 7.74 overnight. That is too low. I recalibrated the probe to ensure that was accurate...and it is.

So the Ca Reactor is now shut off, and the Kalk reactor will be running all night..and I've got to figure out how to get the tank some fresh air. (both the tank and I need to vent some CO2!!)

I hope I'm right about this. Stay tuned...might be a few days before I know if I'm right. I hope I have that much time...
