Back from the dead
I'm bringing this back from the dead to see if anyone has any experience on the topic.
After having the tank for a year now, everything is rock stable, bioload is very low, and algae is completely gone, save for purposely cultivated macros(Chaeto, Caulerpa, Halymedia(?? the red algae)), and corals are thriving.
The pH, however, remains low. Alk is still 9.5, yet pH remains at 7.8. I'm starting to dose kalk, but I'm still curious as to the top off water idea...
How would adding crushed coral/aragonite to my pH6.0 topoff water not raise pH? it's the same principle as a calcium reactor, just on a much smaller scale.
