I have two tanks that I monitor water quality on a regualr basis. However, I have just noticed that one of the tanks GH has dramatically changed to 180PPM from 40 PPM . The only difference about the tank in question is C02 injection and regular dosing with Tropica fertilisers. Both have the same gravel substrate, live plants, bogwood etc from the same source.
I have also double checked the the results with differnet test kits to eliminate a bad reading.
Tap water GH 30 PPM & KH 40 PPM
The tank I am concened about:
PH 7 to 6 with Co2
NO3 20 PPM
N02 0 PPM
GH 180PPM
KH 40 PPM
The other tank;
PH 7
NO3 0.5 PPM
N02 0 PPM
GH 30 PPM
KH 40 PPM
I am concerned if the high GH is detrimental to the fish or plant growth. However, there are no adverse signs.
Also could this be result of the fertiliser dosing and CO2 affecting the reading ?
I just don't know what is happening or why ! I would only expect the CO2 to change the PH.
Your thoughts and advice would be appreciated.
