I took a sample of aquarium water, stirred it indoors for a few seconds w/ pH meter. The water indoors maintained a pH of 8.17. I took it outside for a few seconds, it immediately jumped to 8.31. Is this CO2 build-up significant enough to be a cause of concern?

This was in 24 hours.

About the same view, one is still green only on its very end tips.

I have had a couple of bubble tip anenomes that seem to lose their green color during transport. Water params are good, strong lighting, anenome is full/sticky but just no green. As I understand it the green color does not come from zooxanthellae, but what does it come from?

thanks, probably anenomes as well?

Thanks Martin, currently my Ca tested in at about 330. As for water changes I do weekly 12-18%. At this rate salt dilution may be my only problem (r/o +kalk mix). Speaking of water changes, I see many reef tanks have animals stacked all the way to the top of the tank. Is there any tried...

Thanks Eric, as I understand it most overshooting w/ Kalk is caused by extreme pH increases. If I add very slowly and test w/ digital pH meter, wouldn't this alleviate the concern of overdosing? Can other overdosing occur w/ Kalk other than pH?

Hi Eric, Not dosing on the Ca very often maybe this is my problem, I think my best bet may just to use Kalk and be careful with it. As I understand it, Kalkwassar/calcium hydroxide will raise pH/Alk and available Calcium all-in-one, is this accurate? I realize that a pH drop at night is...

Yes, the pH is dropping from 8.35 to 8.15 w/n 24h. The problem is that my xenia stops pulsing below 8.3, above it, it pulses very frequently. My ORP (oxygen redox potential) is at 260, my Alk well over >= 300ppm. ...of course my dosing methods with seachem buffer can't really raise above...

Hello Everyone, I'm a bit new this hobbie and I find myself still confused over pH & Alk after reading various articles around the web. Tank in question is a 46g reef w/ 6w per gal compact lighting. How do I get in a situation with high alkalinity and dropping pH (8.31-8.35 dropping to...
