Phosphates in a daily swing

[Marc2952]

You maybe right, but if it’s the Hanna test kit he’s using you also have to factor in human error as well, I would think this is more likely the reason for the different lvls, more likely than the po4 fluctuating as his results seems to be suggesting.

Ok update i added fluconazole since i was dealing with some bryopsis patches on the rocks and the phosphate has started to stabilize since i added it last night. Does bryopsis really pull that much phosphates like that? Now i just gotta figure out how to keep it stable after the treatment is done.
