Hi Guys,
I've been curious about this for some time and really dont understand whats going on.
So.. here is whats in the tank:
Tropica plant substrate
Seachem Onyx Sand
Redmoor Wood
Dragon rock
A test of the tank water on the first attempt took 26 drops of a Nutrafin testkit. Thats 14.5 kh.
Next I test the tap water straight out the tap... that comes out at 10 drops which is 5.7kh
I go back to the tank and then get a 21 drops kh of 11.7
I understand that on the first test of the tank the test tube could have had some residule salts from drying naturally so that probably explains the slight increase in kh there.
But what the hell has raised my tank KH by nearly 10kh if the tap water is 6 at most?
I've been wondering about this for some time and i initially thought I had harder water out the tap but havent tested this for bout a year so perhaps somethings changed on that front.
Can anyone she some light on this?
Lee
