This morning the water has cleared and the CaCO3 partially dissolved and
partially settled. The tank looks either (and take your pick) like someone
had split a whole bunch of blow into it, or a twisted aquascaper's idea of a
winter wonderland with tropical plants. Everything is coated in a thin
white powder like (here another one!) a made up geisha. Okay, I exaggerate,
but its powdery out there! pH is over 8.0 and KH between 1-2 deg. I figure
KH will keep rising as the CaCo3 dissolves. To counteract the pH, I've
turned on the CO2.

I personly think something might be wrong with your readings. If the pH is
up to 8.0 it is normaly one indicator that your water is hard. The fact that
your KH readings are only 1-2 degrees to me indicate that they are not reading
the specific minerals creating your hardness. There are several hardning
solutions like RO-Right which do not show up on a normal Tetra hardness
test kit while using a TDS meter indicates that the harness is there.
The other thing is that the CaCO3 you added appears to have disolved and then
recrystalized from your discription. To me this could also mean that it has
hit
its saturation point and cannot be further disolved in the water.
Out of curiosity what is your water source? Are you using softened water?
What means are you using to soften the water?
