Re: [APD] Mearuring Ph and CO2

[Vaughn Hopkins <hoppycalif at yahoo_com>]

Bill, if you are experienced, just cranking up the CO2 a tad is  
probably all you need to know.  But, for those of us with less  
experience it is much more difficult.  We can't really tell if we  
have almost enough or far from enough CO2 because we don't have the  
experience to "read the tank".  Since we know the fish will suffer if  
we crank up the CO2 too much, we are hesitant to go past the point  
where the fish just might be suffering.  But, what we see as fish  
suffering a bit, may actually be normal behavior for those fish.  So,  
a means to actually know how much CO2 is in the tank is very valuable  
to us.  And, the only way I have found to do that is to use the  
little doodad that has  known "pure" KH water in it, the same ppm of  
CO2 as the tank, and whose pH I can determine.
