oxygen.....

Mind you, most tank water contains organic acids rather than extra buffers, so tends to read a lower pH (and therefore overestimates CO2). The overall picture on the thread seems to be of a tank without enough CO2 (slow bubble rate, plants not pearling).

Given that, I'd imagine we're looking at a low O2 problem rather than a high CO2 one.

I have no idea why Red Sea puts that horrible piece of info in the instructions, its just as bad as the ebay drop checkers, they state to use distilled, which does nothing either.
