Hi I am currently cycling my new 20g planted tank (day 7 only, cycle not yet completed).
I have tested PH/GH/KH and here are the results :
PH = 8.2
GH = 40 mg/l (soft)
KH = 30 mg/l
I am confused my test kit says that such a low Kh "Is normally associated with a low pH". But my PH seems to be on the high side (too much maybe?).
Also, I read having soft water with such a high PH could be risky (fluctuating). Should I do anything about it like raising the GH/KH or lowering the PH?
Or should I wait for cycle to complete then retest parameters (not sur if it should change or not).
Here are the plants I have right now :
- Java fern
- Java moss
- Amazon sword
All are doing fine so far except for the java fern whose leaves are turning blackish and start growing what seems to be hair algae.
I am also cycling with fish (3 x cherry barb) and they are know to like KH 4-10, pH 6.0-7.0...
So now I'm afraid I might have compromised the health of my cherry bard.
Any thought on what I should do next?
