pH low... how to adjust?
- Thread starter bigredspecial

OK, ignoring the ongoing alkalinity debatewhich with alk at 9.5 is fairly irrelevant, if you're at 8 in a bucket, and unstable 7.7 to 7.9 in the tank, I would bet it's CO2 in the tank varying with photosynthesis. Do you have a skimmer , or sump? How big tank, how much live rock, how many fishies and so on.....
The Fool, the tank is 10g, no sump, no skimmer. As I've mentioned before, there are no fish or inverts(save for hitchhikers) in there yet - tank is cycling. there are 8lbs LR. There is a small amount of cyanno, brown algae is gaining a foothold, and hair algae is growing relatively rampant, but not enough to alter pH, IMO.
I have another idea in my head now - while the tank pH is too high to effectively dissolve aragonite or crushed coral, my RO water has a pH of 6.0... so, in theory at least, adding a pound or two to the bottle(5gal) should raise it a bit.
has anyone else tried anything like this?

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.
