Re: Why does KH drop?
In my last post about kH dropping in a Flourite tank, I forgot to say
that it *wasn't* due to lack of CO2. I had the tank set up before for
a "dry run" with everything on it but the substrate, for about 2 months.
I used that period to check the plumbing and the water change system, adjust
the CO2 injection, and grow a large enough mass of plants to start the tank.
Mostly penywort, ambulia, hygro and frogbit. CO2 was kept at about 40-50 ppm
all the time. When I set up the tank with the Flourite substrate, I used the
same plants, and the same PMDD based fertilization regime. That is, nothing
changed significantly but the substrate. That's why I tend to disregard the
plants as a possible cause of the kH drop.
