Re: CO2 Measurement etc



Roger,

I would tend to look somewhere else in your system for problems rather
than a CO2 deficiency.  Firstly, do you measure your iron content to see
if you are adding enough dupla fertilizer.  Secondly, are you using the
whole Dupla system, particularly Duplagan.  Lots of people don't seem
to use Duplagan but the other Dupla fertilizers don't contain Mg.
Thridly, do you use laterite?  Fourthly, how often do you do water
changes?  And, how much light do you have? (watts/gal & dimensions of
the tank please).

Joanne.
